A dissertation (also called thesis or disquisition) is a document that presents the author's research and findings and is submitted in support of candidature for a degree or professional qualification. Theses have been published at Virginia Tech since 1903. Dissertations and Theses have been submitted electronically since 1996, with most of these freely available online through VTechWorks. The Virginia Tech Libraries owns a limited number of theses or dissertations published at other colleges and universities; expect to obtain most of these documents via interlibrary loan. In addition to the search tools referenced below, most subject specific databases (like PsycInfo, Sociological Abstracts, and Engineering Village) will provide citations for theses and dissertations in their covered fields.
Search for these or dissertations in Discovery Search
Discovery Search includes all Virginia Tech theses and dissertations (print and electronic), all of NDLTD and other open access repositories, and all the international dissertations from CRL. It does not include content from ProQuest Dissertations & Theses Global, so you must search that in addition to Discovery Search.
To limit searches to just Virginia Tech published theses or dissertations, include the phrase "Virginia Polytechnic Institute" with quotes in your search. To limit to documents from particular departments, include the department name in quotes. Over time, many departments have changed names, so you will need to search each variation of the department name.

International theses and dissertations
Theses and dissertations published outside the United States will be more difficult to obtain. Interlibrary Loan will not borrow from libraries outside North America. Recently published documents may be available online. Use these tools to search for international theses and dissertations:
- Center for Research Libraries
- The Center for Research Libraries holds more than 800,000 doctoral dissertations from universities outside of the U.S. and Canada. The collection was built by deposits from member libraries and current exchange or depository arrangements with almost 100 universities. Interlibrary loan can borrow from CLR; CRL will also attempt to purchase dissertations not in their collection from foreign institutions. Be aware that purchasing dissertations takes time.
- Theses Canada
- Allows searching for full-text, electronic versions of Canadian dissertations and theses, a collaborative program between the Library and Archives Canada and Canadian universities, established in 1965.
- EThOS from the British Library

Click on Appliquer to save your selection and proceed with the search.

It is at the service of researchers affiliated with academic institutions, whether public or private.

The archive is also accessible to researchers affiliated with foreign academic institutions, whether public or private.
Purchase dissertations through Dissertation Express
