Advisory note

If you are starting from scratch we recommend using biblatex because that package provides localization in several languages, it’s actively developed and makes bibliography management easier and more flexible.

Introduction

Many tutorials have been written about what \(\mathrm{Bib\TeX}\) is and how to use it . However, based on our experience of providing support to Overleaf’s users, it’s still one of the topics that many newcomers to \(\mathrm{\LaTeX}\) find complicated—especially when things don’t go quite right; for example: citations aren’t appearing; problems with authors’ names; not sorted to a required order; URLs not displayed in the references list, and so forth.

In this article we’ll pull together all the threads relating to citations, references and bibliographies, as well as how Overleaf and related tools can help users manage these.

We’ll start with a quick recap of how \(\mathrm{Bib\TeX}\) and bibliography database ( .bib ) files work and look at some ways to prepare .bib files. This is, of course, running the risk of repeating some of the material contained in many online tutorials, but future articles will expand our coverage to include bibliography styles and biblatex —the alternative package and bibliography processor.

Bibliography: just a list of \bibitems

Let’s first take a quick look “under the hood” to see what a \(\mathrm{\LaTeX}\) reference list is comprised of—please don’t start coding your reference list like this because later in this article we’ll look at other, more convenient, ways to do this.

A reference list really just a thebibliography list of \bibitems :

By default, this thebibliography environment is a numbered list with labels [1] , [2] and so forth. If the document class used is article , \begin{thebibliography} automatically inserts a numberless section heading with \refname (default value: References ). If the document class is book or report, then a numberless chapter heading with \bibname (default value: Bibliography ) is inserted instead. Each \bibitem takes a cite key as its parameter, which you can use with \cite commands, followed by information about the reference entry itself. So if you now write

together with the thebibliography block from before, this is what gets rendered into your PDF when you run a \(\mathrm{\LaTeX}\) processor (i.e. any of latex , pdflatex , xelatex or lualatex ) on your source file:

Figure 1: Citing entries from a thebibliography list.

Notice how each \bibitem is automatically numbered, and how \cite then inserts the corresponding numerical label.

\begin{thebibliography} takes a numerical argument: the widest label expected in the list. In this example we only have two entries, so 9 is enough. If you have more than ten entries, though, you may notice that the numerical labels in the list start to get misaligned:

Figure 2: thebibliography with a label that’s too short.

We’ll have to make it \begin{thebibliography}{99} instead, so that the longest label is wide enough to accommodate the longer labels, like this:

Figure 3: thebibliography with a longer label width.

If you compile this example code snippet on a local computer you may notice that after the first time you run pdflatex (or another \(\mathrm{\LaTeX}\) processor), the reference list appears in the PDF as expected, but the \cite commands just show up as question marks [?] .

This is because after the first \(\mathrm{\LaTeX}\) run the cite keys from each \bibitem ( texbook , lamport94 ) are written to the .aux file and are not yet available for reading by the \cite commands. Only on the second run of pdflatex are the \cite commands able to look up each cite key from the .aux file and insert the corresponding labels ( [1] , [2] ) into the output.

On Overleaf, though, you don’t have to worry about re-running pdflatex yourself. This is because Overleaf uses the latexmk build tool , which automatically re-runs pdflatex (and some other processors) for the requisite number of times needed to resolve \cite outputs. This also accounts for other cross-referencing commands, such as \ref and \tableofcontents .

A note on compilation times

Processing \(\mathrm{\LaTeX}\) reference lists or other forms of cross-referencing, such as indexes, requires multiple runs of software—including the \(\mathrm{\TeX}\) engine (e.g., pdflatex ) and associated programs such as \(\mathrm{Bib\TeX}\), makeindex , etc. As mentioned above, Overleaf handles all of these mulitple runs automatically, so you don’t have to worry about them. As a consequence, when the preview on Overleaf is refreshing for documents with bibliographies (or other cross-referencing), or for documents with large image files (as discussed separately here ), these essential compilation steps may sometimes make the preview refresh appear to take longer than on your own machine. We do, of course, aim to keep it as short as possible! If you feel your document is taking longer to compile than you’d expect, here are some further tips that may help.

Enter \(\mathrm{Bib\TeX}\)

There are, of course, some inconveniences with manually preparing the thebibliography list:

• It’s up to you to accurately format each \bibitem based on the reference style you’re asked to use—which bits should be in bold or italic? Should the year come immediately after the authors, or at the end of the entry? Given names first, or last names first?
• If you’re writing for a reference style which requires the reference list to be sorted by the last names of first authors, you’ll need to sort the \bibitem s yourself.
• For different manuscripts or documents that use different reference styles you’ll need to rewrite the \bibitem for each reference.

This is where \(\mathrm{Bib\TeX}\) and bibliography database files ( .bib files) are extremely useful, and this is the recommended approach to manage citations and references in most journals and theses. The biblatex approach, which is slightly different and gaining popularity, also requires a .bib file but we’ll talk about biblatex in a future post.

Instead of formatting cited reference entries in a thebibliography list, we maintain a bibliography database file (let’s name it refs.bib for our example) which contains format-independent information about our references. So our refs.bib file may look like this:

You can find more information about other \(\mathrm{Bib\TeX}\) reference entry types and fields here —there’s a huge table showing which fields are supported for which entry types. We’ll talk more about how to prepare .bib files in a later section.

Now we can use \cite with the cite keys as before, but now we replace thebibliography with a \bibliographystyle{...} to choose the reference style, as well as \bibliography{...} to point \(\mathrm{Bib\TeX}\) at the .bib file where the cited references should be looked-up.

This is processed with the following sequence of commands, assuming our \(\mathrm{\LaTeX}\) document is in a file named main.tex (and that we are using pdflatex ):

• pdflatex main
• bibtex main

and we get the following output:

Figure 4: \(\mathrm{Bib\TeX}\) output using the plain bibliography style.

Whoah! What’s going on here and why are all those (repeated) processes required? Well, here’s what happens.

During the first pdflatex run, all pdflatex sees is a \bibliographystyle{...} and a \bibliography{...} from main.tex . It doesn’t know what all the \cite{...} commands are about! Consequently, within the output PDF, all the \cite{...} commands are simply rendered as [?], and no reference list appears, for now. But pdflatex writes information about the bibliography style and .bib file, as well as all occurrences of \cite{...} , to the file main.aux .

It’s actually main.aux that \(\mathrm{Bib\TeX}\) is interested in! It notes the .bib file indicated by \bibliography{...} , then looks up all the entries with keys that match the \cite{...} commands used in the .tex file. \(\mathrm{Bib\TeX}\) then uses the style specified with \bibliographystyle{...} to format the cited entries, and writes a formatted thebibliography list into the file main.bbl . The production of the .bbl file is all that’s achieved in this step; no changes are made to the output PDF.

When pdflatex is run again, it now sees that a main.bbl file is available! So it inserts the contents of main.bbl i.e. the \begin{thebibliography}....\end{thebibliography} into the \(\mathrm{\LaTeX}\) source, where \bibliography{...} is. After this step, the reference list appears in the output PDF formatted according to the chosen \bibliographystyle{...} , but the in-text citations are still [?].

pdflatex is run again, and this time the \cite{...} commands are replaced with the corresponding numerical labels in the output PDF!

As before, the latexmk build tool takes care of triggering and re-running pdflatex and bibtex as necessary, so you don’t have to worry about this bit.

Some notes on using \(\mathrm{Bib\TeX}\) and .bib files

A few further things to note about using \(\mathrm{Bib\TeX}\) and .bib files :

• You may have noticed that although refs.bib contained five \(\mathrm{Bib\TeX}\) reference entries, only two are included in the reference list in the output PDF. This is an important point about \(\mathrm{Bib\TeX}\): the .bib file’s role is to store bibliographic records, and only entries that have been cited (via \cite{...} ) in the .tex files will appear in the reference list. This is similar to how only cited items from an EndNote database will be displayed in the reference list in a Microsoft Word document. If you do want to include all entries—to be displayed but without actually citing all of them—you can write \nocite{*} . This also means you can reuse the same .bib file for all your \(\mathrm{\LaTeX}\) projects: entries that are not cited in a particular manuscript or report will be excluded from the reference list in that document.
• \(\mathrm{Bib\TeX}\) requires one \bibliographystyle{...} and one \bibliography{...} to function correctly—in future posts we’ll see how to create multiple bibliographies in the same document. If you keep getting “undefined citation” warnings, check that you have indeed included those two commands, and that the names are spelled correctly. File extensions are not usually required, but bear in mind that file names are case sensitive on some operating systems—including on Overleaf! Therefore, if you typed \bibliographystyle{IEEetran} (note the typo: “e”) instead of \bibliographystyle{IEEEtran} , or wrote \bibliography{refs} when the actual file name is Refs.bib , you’ll get the dreaded [?] as citations.
• In the same vein, treat your cite keys as case-sensitive, always. Use the exact same case or spelling in your \cite{...} as in your .bib file.
• The order of references in the .bib file does not have any effect on how the reference list is ordered in the output PDF: the sorting order of the reference list is determined by the \bibliographystyle{...} . For example, some readers might have noticed that, within my earlier example, the first citation in the text latex2e is numbered [2], while the second citation in the text ( texbook ) is numbered [1]! Have \(\mathrm{\LaTeX}\) and \(\mathrm{Bib\TeX}\) lost the plot? Not at all: this is actually because the plain style sorts the reference list by alphabetical order of the first author’s last name . If you prefer a scheme where the numerical citation labels are numbered sequentially throughout the text, you’ll have to choose a bibliography style which implements this. For example, if instead we had used \bibliographystyle{IEEEtran} for that example, we’d get the following output. Notice also how the formatting of each cited item in the reference list has automatically updated to suit the IEEE’s style:

Figure 5: IEEEtran bibliography style output.

We’ll talk more about different bibliography styles, including author–year citation schemes, in a future article. For now, let’s turn our attention to .bib file contents, and how we can make the task of preparing .bib files a bit easier.

Taking another look at .bib files

As you may have noticed earlier, a .bib file contains \(\mathrm{Bib\TeX}\) bibliography entries that start with an entry type prefixed with an @ . Each entry has a some key–value \(\mathrm{Bib\TeX}\) fields , placed within a pair of braces ( {...} ). The cite key is the first piece of information given within these braces, and every field in the entry must be separated by a comma :

As a general rule, every bibliography entry should have an author , year and title field, no matter what the type is. There are about a dozen entry types although some bibliography styles may recognise/define more; however, it is likely that you will most frequently use the following entry types:

• @article for journal articles (see example above).
• @inproceedings for conference proceeding articles:
• @book for books (see examples above).
• @phdthesis , @masterthesis for dissertations and theses:
• @inbook is for a book chapter where the entire book was written by the same author(s): the chapter of interest is identified by a chapter number:
• @incollection is for a contributed chapter in a book, so would have its own author and title . The actual title of the entire book is given in the booktitle field; it is likely that an editor field will also be present:
• you will often find it useful to add \usepackage{url} or \usepackage{hyperref} in your .tex files’ preamble (for more robust handling of URLs);
• not all bibliography styles support the url field: plain doesn’t, but IEEEtran does. All styles support note . More on this in a future post;
• you should be mindful that even web pages and @misc entries should have an author , a year and a title field:

Multiple authors in \(\mathrm{Bib\TeX}\)

In a .bib file, commas are only used to separate the last name from the first name of an author—if the last name is written first. Individual author names are separated by and . So these are correct:

But none of the following will work correctly —you’ll get weird output, or even error messages from \(\mathrm{Bib\TeX}\)! So take extra care if you are copying author names from a paper or from a web page.

Multiple-word last names

If an author’s last name is made up of multiple words separated by spaces, or if it’s actually an organisation, place an extra pair of braces around the last name so that \(\mathrm{Bib\TeX}\) will recognise the grouped words as the last name:

Alternatively, you can use the Lastname, Firstname format; some users find that clearer and more readable:

Remember: Whether the first or last name appears first in the output (“John Doe” vs “Doe, John”), or whether the first name is automatically abbreviated “J. Doe” or “Doe, J.” vs “John Doe” “J. Doe”), all such details are controlled by the \bibliographystyle .

I tried to use % to comment out some lines or entries in my .bib file, but I got lots of error messages instead?

% is actually not a comment character in .bib files! So, inserting a % in .bib files not only fails to comment out the line, it also causes some \(\mathrm{Bib\TeX}\) errors. To get \(\mathrm{Bib\TeX}\) to ignore a particular field we just need to rename the field to something that \(\mathrm{Bib\TeX}\) doesn’t recognise. For example, if you want to keep a date field around but prefer that it’s ignored (perhaps because you want \(\mathrm{Bib\TeX}\) to use the year field instead) write Tdate = {...} or the more human-readable IGNOREdate = {...} .

To get \(\mathrm{Bib\TeX}\) to ignore an entire entry you can remove the @ before the entry type. A valid reference entry always starts with a @ followed by the entry type; without the @ character \(\mathrm{Bib\TeX}\) skips the lines until it encounters another @ .

How/where do I actually get those .bib files?

Edit the .bib file as plain text.

Because .bib files are plain text you can certainly write them by hand—once you’re familiar with \(\mathrm{Bib\TeX}\)’s required syntax. Just make sure that you save it with a .bib extension, and that your editor doesn’t surreptitiously add a .txt or some other suffix. On Overleaf you can click on the “Files…” link at the top of the file list panel, and then on “Add blank file” to create a fresh .bib file to work on.

Pro tip: Did you know that Google Scholar search results can be exported to a \(\mathrm{Bib\TeX}\) entry? Click on the “Cite” link below each search result, and then on the “\(\mathrm{Bib\TeX}\)” option search. You can then copy the \(\mathrm{Bib\TeX}\) entry generated. Here’s a video that demonstrates the process. Note that you should always double-check the fields presented in the entry, as the automatically populated information isn’t always comprehensive or accurate!

Help from GUI-based .bib editors

Many users prefer to use a dedicated \(\mathrm{Bib\TeX}\) bibliography database editor/manager, such as JabRef or BibDesk to maintain, edit and add entries to their .bib files. Using a GUI can indeed help reduce syntax and spelling errors whilst creating bibliography entries in a \(\mathrm{Bib\TeX}\) file. If you prefer, you can prepare your .bib file on your own machine using JabRef, BibDesk or another utility, and then upload it to your Overleaf.

Pro tip: If you’d like to use the same .bib for multiple Overleaf projects, have a look at this help article to set up a “master project”, or this one for sharing files from Google Drive (the instructions apply to other cloud-based storage solutions, such as Dropbox).

Export from reference library services

If you click on the Upload files button above the file list panel, you'll notice some options: Import from Mendeley, and Import from Zotero. If you’re already using one of those reference library management services, Overleaf can now hook into the Web exporter APIs provided by those services to import the .bib file (generated from your library) into your Overleaf project. For more information, see the Overleaf article How to link your Overleaf account to Mendeley and Zotero .

For other reference library services that don’t have a public API, or are not yet directly integrated with Overleaf, such as EndNote or Paperpile , look for an “export to .bib ” option in the application or service. Once you have a .bib file, you can then add it to your Overleaf project.

I’ve already got a reference list in a Microsoft Word/HTML/PDF file; can I somehow reuse the data without re-typing everything?

It used to be that you would have to hand-code each line into a \bibitem or an @article{...} entry (or another entry type) in a .bib file. As you can imagine, it’s not exactly a task that many people look forward to. Fortunately, these days some tools are available to help. They typically take a plain text file, e.g.

and attempt to parse the lines, converting it into a structured bibliography as a \(\mathrm{Bib\TeX}\) .bib file. For example, have a look at text2bib or Edifix . Be sure to go through the options of these tools carefully, so that they work well with your existing unstructured bibliography in plain text.

Summary and further reading

We’ve had a quick look at how \(\mathrm{Bib\TeX}\) processes a .bib bibliography database file to resolve \cite commands and produce a formatted reference list, as well as how to prepare .bib files.

Happy \(\mathrm{Bib\TeX}\)ing!

Managing References

BibTeX is a file format used for lists of references for LaTeX documents. Many citation management tools support the ability to export and import lists of references in .bib format. Some reference management tools can generate BibTeX files of your library or folders for use in your LaTeX documents.

LaTeX on Wikibooks has a Bibliography Management page.

How to get started writing your thesis in LaTeX

Writing a thesis or dissertation in LaTeX can be challenging, but the end result is well worth it - nothing looks as good as a LaTeX-produced pdf, and for large documents it's a lot easier than fighting with formatting and cross-referencing in MS Word. Review this video from Overleaf to help you get started writing your thesis in LaTeX, using a standard thesis template from the Overleaf Gallery .

You can upload your own thesis template to the Overleaf Gallery if your university provides a set of LaTeX template files or you may find your university's thesis template already in the Overleaf Gallery.

This video assumes you've used LaTeX before and are familiar with the standard commands (see our other tutorial videos  if not), and focuses on how to work with a large project split over multiple files.

Guide to Writing Your Thesis in LaTeX

The bibliography and list of references.

The Graduate School requires a Bibliography which includes all the literature cited for the complete thesis or dissertation. Quoting from the Graduate School’s Guidelines for the Format of Theses and Dissertations :

“Every thesis in Standard Format must contain a Bibliography which lists all the sources used or consulted in writing the entire thesis and is placed at the very end of the work. The complete citations are arranged alphabetically by last name of the author. Individual citations are not numbered. No abbreviations in titles of published works will be accepted. The full title of a book, journal, website, proceedings, or any other published work must be italicized or underlined. Citations must follow standards set by the style manual that the student is using. The bibliography for URI theses is not broken into categories.”

The List of References is not required by the Graduate School, but is the style commonly used in Engineering, Mathematics, and many of the Sciences. It consists of a numbered list of the sources used or consulted in writing the thesis in the order that they are referenced in the text. There can be either one List of References for the entire thesis, or a List of References at the end of each chapter.

Both the Bibliography and the List of References will be generated by the urithesis LaTeX class. All you need to do is add information about your sources to the references.bib file, which is a database containing all of the necessary information about the references, then cite the reference in your thesis using the \cite{} command.

Generating the Bibliography and References

The bibliography and list of references are generated by running BibTeX. To generate the bibliography, load the file thesisbib.tex into your editor, then run BibTeX on it.

If each chapter has its own list of references, you will need to run BibTeX on each chapter to update its list of references. If there is one list of references for the whole thesis (because you used the oneref option, you will only need to run BibTeX on the top level file thesis.tex .

How to Add a Bibliography Entry

When we want to refer to a source in the thesis, we place an entry for that source in the file references.bib , then cite the source in the thesis with the \cite{LABEL} command. The syntax for an entry in the references.bib file is of the form:

ENTRYTYPE is the type of bibliographic entry such as Book , Article , or TechReport , that this entry describes. At the end of this page is a list of all possible entry types .

LABEL is a unique string that is used to refer to this entry in the body of the thesis when using the \cite{LABEL} command.

The FIELDNAMEn entries are the fields that describe this entry, (ie. author, title, pages, year, etc.). Each entry type has certain required fields and optional fields. See the list of all entry types for a description of the available fields.

As an example, suppose we have a paper from a conference proceedings that we want to cite. First we make an entry in the our references.bib file of the form:

We then cite this source in the text of our thesis with the command \cite{re:toolan:as03} . This will generate a Bibliography entry that looks something like:

and a List of References entry that looks something like:

Types of List of References

The Graduate School requires that the bibliography is always at the end of the thesis and sorted alphabetically by author, therefore there is no options that affect it. The list of references is optional, therefore there are a few different ways that it can created.

By default a separate list of references appears at the end of each chapter, and are sorted by the order that they are cited in that chapter. The option oneref (see options ) will create a single list of references for the whole thesis, which due to the requirements of the Graduate School, will appear after the last chapter and before any appendices.

The option aparefs will cite references using the APA style, which is the last name of the author and year of publication, such as (Toolan, 2006), instead of the default IEEE style, which is a number, such as [1]. This option will also sort the references alphabetically by author, instead of in order of citation. The options oneref and aparefs can be used together to create a single list of references using the APA style.

Supported Bibliography Entry Types

The following is a list of all the entry types that can be used. Click on the desired type to see a detailed description of how to use that type.

• Article – An article from a journal or magazine
• Book – A book with an explicit publisher
• InBook – A part of a book, such as a chapter or selected page(s)
• InCollection – A part of a book having its own title
• Booklet – Printed and bound works that are not formally published
• Manual – Technical documentation
• InProceedings – An article in a conference proceedings
• Proceedings – The entire proceedings of a conference
• MastersThesis – A Master’s thesis
• PhDThesis – A Ph.D. dissertation
• TechReport – A report published by a school or other institution
• Unpublished – A document that has not been formally published
• Electronic – An internet reference like a web page
• Patent – A patent or patent application
• Periodical – A magazine or journal
• Standard – Formally published standard
• Misc – For use when nothing else fits

Articles that have not yet been published can be handled as a misc type with a note. Sometimes it is desirable to put extra information into the month field such as the day, or additional months. This is accomplished by using the BIBTEX concatenation operator “#“:

Example .bib using this type:

Books may have authors, editors or both. Example .bib using this type:

Inbook is used to reference a part of a book, such as a chapter or selected page(s). The type field can be used to override the word chapter (for which IEEE uses the abbreviation “ch.”) when the book uses parts, sections, etc., instead of chapters

Incollection is used to reference part of a book having its own title. Like book , incollection supports the series, chapter and pages fields. Also, the type field can be used to override the word chapter.

Booklet is used for printed and bound works that are not formally published. A primary difference between booklet and unpublished is that the former is/was distributed by some means. Booklet is rarely used in bibliographies.

Technical documentation is handled by the manual entry type.

References of papers in conference proceedings are handled by the inproceedings or conference entry type. These two types are functionally identical and can be used interchangeably. Example .bib using this type:

It is rare to need to reference an entire conference proceedings, but, if necessary, the proceedings entry type can be used to do so.

Master’s (or minor) theses can be handled with the mastersthesis entry type. The optional type field can be used to override the words “Master’s thesis” if a different designation is desired:

The phdthesis entry type is used for Ph.D. dissertations (major theses). Like mastersthesis , the type field can be used to override the default designation. Example .bib using this type:

Techreport is used for technical reports. The optional type field can be used to override the default designation “Tech. Rep.” Example .bib using this type:

The unpublished entry type is used for documents that have not been formally published. IEEE typically just uses “unpublished” for the required note field.

The electronic entry type is for internet references. IEEE formats electronic references differently by not using italics or quotes and separating fields with periods rather than commas. Also, the date is enclosed within parentheses and is placed closer to the title. This is probably done to emphasize that electronic references may not remain valid on the rapidly changing internet. Note also the liberal use of the howpublished field to describe the form or category of the entries. The organization and address fields may also be used. Example .bib using this type:

The nationality field provides a means to handle patents from different countries

The nationality should be capitalized. The assignee and address (of the assignee) fields are not used, however, they are provided. The type field provides a way to override the “patent” description with other patent related descriptions such as “patent application” or “patent request”:

The periodical entry type is used for journals and magazines.

The standard entry type is used for formally published standards. Alternatively, the misc entry type, along with its howpublished field, can be used to create references of standards.

Misc is the most flexible type and can be used when none of the other entry types are applicable. The howpublished field can be used to describe what exactly (or in what form) the reference is (or appears as). Possible applications include technical-report-like entries that lack an institution, white papers and data sheets.

Additional Comments

Because we are effectively creating multiple bibliographies, (one for the actual bibliography, and one for each list of references), the two LATEX commands \bibliographystyle{} and \bibliography{} are not used. They have been redefined to do nothing, and the equivalent of these commands are done automatically when necessary.

When there is a reference that should be included in the bibliography, but does not need to be explicitly referenced in the thesis, use the \nocite{} command. This command works like the \cite{} command, except it does not put the citation in the list of references, only in the bibliography. The \nocite{} command must appear after the first \newchapter{} command, or it will be ignored.

When using the option aparefs , and a citation does not have an author, (such as often occurs with a web page), the key field can be used to specify what to use in the citation instead of the author’s name.

About the Bibliography Format

The bibliography format used by the urithesis class is based on the IEEE format. See the article “How to Use the IEEEtran BIBTEX Style” by Michael Shell for more details.

Tips on Writing a Thesis in LaTeX

A typical scientific document contains a number of references, and this leads to the problem of organizing and presentation of the references in the document. The problem can be subdivided into several parts: store of the reference information, later retrieval of this information while preparing the document, and presentation (formatting) of the reference information in the document and in the bibliography according to a particular format.

A widely-used approach to deal with references in LaTeX documents is to employ BibTeX reference management software. In BibTeX reference information is stored in format-independent plain text file(s) (usually with .bib extension), which can be modified with almost any text editor. Such a text file contains BibTeX entries , and each entry, formed by several text lines, has

• unique ID or key , needed to identify and refer to the particular entry, for instance Author2001 ;
• entry type , which can be article , book , thesis , etc.;
• entry fields (such as year , publisher , journal , etc.), corresponding to the particular type.

Here is an example of the article type entry from the .bib file I used while typesetting thesis:

The command \bibliography { reference_list } placed before \begin { document } is used to specify a plain text input file ( reference_list.bib here) containing information on references.

References can be "cited" during editing the LaTeX document using, for example, \cite { key } command, and later at the document compilation step LaTeX input files must be processed with LaTeX and BibTeX .

The most popular approaches to indicate a reference appearing in the text can be classified as "numeric" and "author–year". The former uses sequential number of a reference in the document

while "author–year" is based on the extended reference information and may appear like this:

Each indication has particular advantages and drawbacks. For example, numeric is more compact (i.e., require less space in a text line), and a group of references can be "compressed" into a range in the case they have sequential numbering (i.e., [1,2,3,5] will be shown as [1–3,5]). On the other hand, author–year indication shows more information on the cited document (typically, first one or two author names, and a year of a publication), but requires more space compared to the numeric one. The space consumed by reference may become important if your document has high density of references (and you care about in-line space "wasted" by references :).

In my thesis I have decided to use "numeric" indication, but contrary to the example above reference numbers appear in the text as a footnote: reference number by itself has script size ,

and each number has associated script-sized text at the bottom of the page (where the reference appeared) containing extended information on the cited reference:

This citation scheme improves in-line space saving compared to the plain numeric indication due to the reduced size of numbers, and at the same time allows the reader to see what exactly was cited without looking in the bibliography (which is typically located at the end of a document or chapter). The drawback of the footnote citation scheme follows from the space consumed at the bottom of the page: if there are too many citations on the page, footnote text will occupy a lot of space. For example:

To create citations in my thesis, I employed the biblatex package, which is one of the most notable packages I have used with LaTeX. The package provides a highly customizable interface for the creation and edit of the presentation of bibliographic data in the document. Compared to the plain BibTeX, biblatex enables relatively easy customization of the appearance of bibliographic data. Below I provide customizations I used to modify the default biblatex output. The detailed description of the biblatex commands is available in the package documentation .

The two basic commands to enable biblatex and output citation list are

While preparing the thesis I activated biblatex with the following options compiling the document using biblatex with the options below will need custom-numeric-comp.bbx and custom-numeric-comp.cbx files (see next sections, "Biblatex customization" and "Footnote citation") :

Option hyperref=true was specified to transform various citation elements (like citation number, page number where citation appears, hyperlink to the web page where cited document can be found, etc.) into clickable hyperlinks. This option requires hyperref package (see also notes on hyperref ).

With options url=false,isbn=false I disabled printing the URLs and ISBNs in the bibliography.

Back references

Option backref=true enables generation of the back references to the citation, which are usually number(s) of the page where citation appears:

The back reference text preceding the page number ("see p.") can be modified using the following command:

Just a note on the back references. When you are reading a .pdf document, encounter a reference, and click on it, .pdf viewer will change view to the record of this reference in the bibliography. Now, if you want to return to the main text and continue reading, you may find it difficult to do using back reference when the reference was cited on several pages (back reference will contain several page numbers and you have to bear in mind the original page number you came to the bibliography), and a good solution here is to use " Alt + ← " instead of the back reference itself. On the other hand, back references are useful to indicate how often and where a particular reference was cited in the document.

Citation style

Option style=custom-numeric-comp determines the citation style. As seen from its name, the chosen citation style uses numbers ( numeric ) to indicate citations in text, and consequent numbers are compressed ( comp ) into a range: [1,2,3,5] is printed as [1–3,5]. Above it was mentioned that I used footnote version of the standard biblatex numeric-comp style — as a result, each citation has i) its number typeset as superscript, and ii) short and extended reference information located at the bottom of the page ("footnote text") and in the bibliography, respectively:

Option citereset=chapter defines biblatex behavior for the reference footnote text in a typical situation when a citation appears several times in the document: footnote text for the particular citation is printed only once per document chapter ( citereset=chapter ), where chapter is defined according to the LaTeX sectioning commands . In my thesis a typical chapter includes about 20 pages, and I assumed citereset=chapter to be quite acceptable. However, one of my colleagues was confused by such a rule for printing the footnote text (i.e., he did not get the logic behind the rule until I have explained it). I was thinking about resetting footnote text as "once-per-page" (not "once-per-chapter") but decided to avoid this due to high density of the references in my thesis. If you are interested in such a behavior some useful information can be found here .

Number of displayed author names

Options maxcitenames=3 and maxbibnames=100 limit number of authors of the cited document to be printed in the document body and in the bibliography, respectively. If the number of authors exceeds maxcite(bib)names , the author list is truncated according to biblatex settings, and usually printed as "Author1 et al." In my case I have very short authors lists in the footnote text (document body) to reduce space occupied by footnote citations,

and virtually all authors are displayed in the bibliography:

I note that I have prepared my thesis with biblatex v. 0.9a (19.03.2010), while this on-line document was prepared and tested on biblatex v. 1.6 (29.07.2011). Options maxcitenames and maxbibnames were not available in v. 0.9a, and the described biblatex behavior (with maxcitenames=3 and maxbibnames=100 ) was obtained using maxnames=3 while loading the biblatex package, and maxnames=100 while printing the bibliography, i.e.

The next section continues the discussion of the biblatex customization.

Check your paper before your teacher does!

Avoid plagiarism — quickly check for missing citations and check for writing mistakes., is this source credible consider the criteria below..

Is the purpose to entertain, sell, persuade, or inform/teach ? Journal articles are often designed to inform or teach. Books and websites could have any of these or a combination of the purposes above. So it is important to determine why the source was created and if it is appropriate for your research. For websites in particular, looking at their "About Us" page or "Mission Statement" can help you evaluate purpose.

Accuracy is the reliability and truthfulness of the source. Here are a few indicators of an accurate source:

• Citations or a works cited list. For websites, this can be links to other credible sites.
• Evidence that backs up claims made by the author(s).
• Text that is free of spelling and grammatical errors.
• Information that matches that in other, credible sources.
• Language that is unbiased and free of emotion.

Based on the above the source could be accurate, inaccurate, a mixture of accurate and inaccurate, or hard to tell.

Authority: Author

The author is the individual or organization who wrote the information in the book, in the journal article, or on the website. If no author is listed, there may be another contributor instead. For example, an editor or a translator. A credible author has:

• Written several articles or books on the topic.
• Provided contact information. For example, an email address, mailing address, social media account, etc.
• The experience or qualifications to be an expert on the topic.

Authority: Publisher

The credibility of the publisher can contribute to the authority of a source. The publisher can be a person, company or organization. Authoritative publishers:

• Accept responsibility for content.
• Are often well-known.
• Often publish multiple works on the same or related topics.

Relevance describes how related or important a source is to your topic. While a source may be credible, it does not necessarily mean it is relevant to your assignment. To determine relevance, you should:

• Determine the website's intended audience. Look at the level of the information and the tone of the writing. For example, is it meant for academics or the general public?
• Make sure that the information is related to your research topic.
• Make sure that the information helps you answer your research question.

A publication date is an important part of evaluating the credibility of a source and its appropriateness for your topic. It is generally best to use content that was recently published or updated, but depending on your assignment, it may be appropriate to use older information. For example, a journal entry from Abraham Lincoln during the Civil War is too outdated to use in a discussion about modern politics and war, but would be appropriate for a paper about the Civil War. Consider the following when evaluating currency:

• Was it published or updated recently? If a website, is there even a publication date listed?
• Is the date of the source appropriate or inappropriate for my assignment?

After analyzing your source, do you believe it is credible, not credible, partially credible, or are you unsure? If you are still unsure, it may help to ask your instructor a librarian for assistance.

Title: facilitating opinion diversity through hybrid nlp approaches.

Abstract: Modern democracies face a critical issue of declining citizen participation in decision-making. Online discussion forums are an important avenue for enhancing citizen participation. This thesis proposal 1) identifies the challenges involved in facilitating large-scale online discussions with Natural Language Processing (NLP), 2) suggests solutions to these challenges by incorporating hybrid human-AI technologies, and 3) investigates what these technologies can reveal about individual perspectives in online discussions. We propose a three-layered hierarchy for representing perspectives that can be obtained by a mixture of human intelligence and large language models. We illustrate how these representations can draw insights into the diversity of perspectives and allow us to investigate interactions in online discussions.

John Joannopoulos receives 2024-2025 Killian Award

The mit physicist is honored for pioneering work in photonics that helped to advance tools for telecommunications and biomedicine..

John Joannopoulos , an innovator and mentor in the fields of theoretical condensed matter physics and nanophotonics, has been named the recipient of the 2024-2025 James R. Killian Jr. Faculty Achievement Award.

Joannopoulos is the Francis Wright Davis Professor of Physics and director of MIT’s Institute for Soldier Nanotechnologies . He has been a member of the MIT faculty for 50 years.

“Professor Joannopoulos’s profound and lasting impact on the field of theoretical condensed matter physics finds its roots in his pioneering work in harnessing ab initio physics to elucidate the behavior of materials at the atomic level,” states the award citation, which was announced at today’s faculty meeting by Roger White, chair of the Killian Award Selection Committee and professor of philosophy at MIT. “His seminal research in the development of photonic crystals has revolutionized understanding of light-matter interactions, laying the groundwork for transformative advancements in diverse fields ranging from telecommunications to biomedical engineering.”

The award also honors Joannopoulos’ service as a “legendary mentor to generations of students, inspiring them to achieve excellence in science while at the same time facilitating the practical benefit to society through entrepreneurship.”

The Killian Award was established in 1971 to recognize outstanding professional contributions by MIT faculty members. It is the highest honor that the faculty can give to one of its members.

“I have to tell you, it was a complete and utter surprise,” Joannopoulos told MIT News shortly after he received word of the award. “I didn’t expect it at all, and was extremely flattered, honored, and moved by it, frankly.”

Joannopoulous has spent his entire professional career at MIT. He came to the Institute in 1974, directly after receiving his PhD in physics at the University of California at Berkeley, where he also earned his bachelor’s degree. Starting out as an assistant professor in MIT’s Department of Physics, he quickly set up a research program focused on theoretical condensed matter physics.

Over the first half of his MIT career, Joannopoulos worked to elucidate the fundamental nature of the electronic, vibrational, and optical structure of crystalline and amorphous bulk solids, their surfaces, interfaces, and defects. He and his students developed numerous theoretical methods to enable tractable and accurate calculations of these complex systems.

In the 1990s, his work with microscopic material systems expanded to a new class of materials, called photonic crystals — materials that could be engineered at the micro- and nanoscale to manipulate light in ways that impart surprising and exotic optical qualities to the material as a whole.

“I saw that you could create photonic crystals with defects that can affect the properties of photons, in much the same way that defects in a semiconductor affect the properties of electrons,” Joannopoulos says. “So I started working in this area to try and explore what anomalous light phenomena can we discover using this approach?”

Among his various breakthroughs in the field was the realization of a  “perfect dielectic mirror” — a multilayered optical device that reflects light from all angles as normal metallic mirrors do, and that can also be tuned to reflect and trap light at specific frequencies. He and his colleagues saw potential for the mirror to be made into a hollow fiber that could serve as a highly effective optical conduit, for use in a wide range of applications. To further advance the technology, he and his colleagues launched a startup, which has since developed the technology into a flexible, fiber-optic “surgical scalpel.”

Throughout his career, Joannopoulos has helped to launch numerous startups and photonics-based technologies.

“His ability to bridge the gap between academia and industry has not only advanced scientific knowledge but also led to the creation of dozens of new companies, thousands of jobs, and groundbreaking products that continue to benefit society to this day,” the award citation states.

In 2006, Joannopoulos accepted the position as director of MIT’s Institute for Soldier Nanotechnologies (ISN), a collaboration between MIT researchers, industry partners, and military defense experts, who seek innovations to protect and enhance soldiers’ survivability in the field. In his role as ISN head, Joannopoulos has worked across MIT, making connections and supporting new projects with researchers specializing in fields far from his own.

“I get a chance to explore and learn fascinating new things,” says Joannopoulos, who is currently overseeing projects related to hyperspectral imaging, smart and responsive fabrics, and nanodrug delivery. “I love that aspect of really getting to understand what people in other fields are doing. And they’re doing great work across many, many different fields.”

Throughout his career at MIT, Joannopoulos has been especially inspired and motivated by his students, many of whom have gone on to found companies, lead top academic and research institutions, and make significant contributions to their respective fields, including one student who was awarded the Nobel Prize in Physics in 1998.

“One’s proudest moments are the successes of one’s students, and in that regard, I’ve been extremely lucky to have had truly exceptional students over the years,” Joannopolous says.

His many contributions to academia and industry have earned Joannopoulos numerous honors and awards, including his election to both the National Academy of Sciences and the American Academy of Arts and Sciences. He is also a fellow of both the American Physical Society and the American Association for the Advancement of Science.

“The Selection Committee is delighted to have this opportunity to honor Professor John Joannopoulos: a visionary scientist, a beloved mentor, a great believer in the goodness of people, and a leader whose contributions to MIT and the broader scientific community are immeasurable,” the award citation concludes.

Mechanical strengthening of perovskite-substrate heterointerface for highly stable solar cells.

Perovskite solar cells (PSCs) have shown power conversion efficiencies (PCEs) of over 26% that rival the crystalline silicon cells, but their projected application was largely postponed by the device instability, particularly the degradation that originated from the defective bottom interfaces. Here, we introduce a cohesive guanidine polymer, as macromolecular glue, to strengthen the buried interface, resulting in mechanically robust and passivated bottom interface. We found that the guanidine motifs can chemically couple the perovskite/substrate layers, and remarkably restrict the interfacial ionic migration and morphology variation under environment stimulus. The resulting solar cells presented over 25% efficiency, and maintained >97.5% of their initial efficiency in long-term operational stability tests with continuous 1-sun illumination at 55 oC for >1600 hours. The geometric impact of these nanostructures during solar cell degradation was further analyzed by finite element simulation, which revealed that the void expansion would disturb the charge carrier distribution and transport for inferior carrier collection and high recombination velocity. Our strategy offers valuable insights into the design and development of long-lifetime perovskite devices with robust and stable interface.
