Definition of thesis

Did you know.

In high school, college, or graduate school, students often have to write a thesis on a topic in their major field of study. In many fields, a final thesis is the biggest challenge involved in getting a master's degree, and the same is true for students studying for a Ph.D. (a Ph.D. thesis is often called a dissertation ). But a thesis may also be an idea; so in the course of the paper the student may put forth several theses (notice the plural form) and attempt to prove them.

Oxford theses

The Bodleian Libraries’ thesis collection holds every DPhil thesis deposited at the University of Oxford since the degree began in its present form in 1917. Our oldest theses date from the early 1920s. We also have substantial holdings of MLitt theses, for which deposit became compulsory in 1953, and MPhil theses.

Since 2007 it has been a mandatory requirement for students to deposit an electronic copy of their DPhil thesis in the Oxford University Research Archive (ORA) , in addition to the deposit of a paper copy – the copy of record. Since the COVID pandemic, the requirement of a paper copy has been removed and the ORA copy has become the copy of record. Hardcopy theses are now only deposited under exceptional circumstances. 

ORA provides full-text PDF copies of most recent DPhil theses, and some earlier BLitt/MLitt theses. Find out more about Oxford Digital Theses, and depositing with ORA .

Finding Oxford theses

The following theses are catalogued on SOLO (the University libraries’ resource discovery tool) :

• DPhil and BLitt and MLitt theses
• BPhil and MPhil theses 
• Science theses

SOLO collates search results from several sources.

How to search for Oxford theses on SOLO

To search for theses in the Oxford collections on SOLO :

• navigate to the SOLO homepage
• click on the 'Advanced Search' button
• click the 'Material Type' menu and choose the 'Dissertations' option
• type in the title or author of the thesis you are looking for and click the 'Search' button.

Also try an “Any field” search for “Thesis Oxford” along with the author’s name under “creator” and any further “Any field” keywords such as department or subject. 

Searching by shelfmarks

If you are searching using the shelfmark, please make sure you include the dots in your search (e.g. D.Phil.). Records will not be returned if they are left out.

Oxford University Research Archive (ORA)

ORA was established in 2007 as a permanent and secure online archive of research produced by members of the University of Oxford. It is now mandatory for students completing a research degree at the University to deposit an electronic copy of their thesis in this archive. 

Authors can select immediate release on ORA, or apply a 1-year or 3-year embargo period. The embargo period would enable them to publish all or part of their research elsewhere if they wish. 

Theses held in ORA are searchable via  SOLO , as well as external services such as EThOS and Google Scholar. For more information, visit the Oxford digital theses guide , and see below for guidance on searching in ORA.

Search for Oxford theses on ORA

Type your keywords (title, name) into the main search box, and use quotes (“) to search for an exact phrase.

Refine your search results using the drop-downs on the left-hand side. These include:

• thesis type (DPhil, MSc, MLitt, etc.)
• subject area (History, Economics, Biochemistry, etc.)
• item date (as a range)
• file availability (whether a full text is available to download or not)

You can also increase the number of search results shown per page, and sort by relevance, date and file availability. You can select and export records to csv or email. 

Select hyperlinked text within the record details, such as “More by this author”, to run a secondary search on an author’s name. You can also select a hyperlinked keyword or subject.
