Theses and dissertations

Virginia Tech ETDs and theses and dissertations in print | Databases that index dissertations | International dissertations | Purchase dissertations through Dissertation Express

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. Theses and dissertations have been submitted electronically since 1996, with most of these freely available online. The Virginia Tech Libraries owns few 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.

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 Portal
Allows searing of AMICUS, Canada's national online catalogue, for bibliographic records of all theses in Library and Archives Canada's theses collection, which was established in 1965 and access to and search of the full text electronic versions of numerous Canadian theses and dissertations.
Canadian Association of Research Libraries Institutional Repository Search Service
Searches institutional repositories that can include theses and dissertations from the colleges and universities that participate.
EThOS from the British Library
Includes theses from over 100 UK institutions, including many that have been digitized and allow open access. If you need non-digitized or restricted access theses, order them via Login to ILLiad which will obtain them through the Center for Research Libraries.
Australian Digital Thesis Project (ADT)
ADT is a national collaborative distributed database of digitized PhD and Masters theses produced at Australian Universities.
SUDOC
An online catalog to holdings at French academic libraries, SUDOC covers theses completed in France since 1972 (for Humanities and Social Sciences). Can be searched by author, title, and abstract, but since this is a comprehensive catalog to resources at French academic libraries, limit your search to theses by clicking on Options on the right hand corner of the page and limiting your search to Theses. Click on Appliquer to save your selection and proceed with the search.
Serveur de Thèses Multidisciplinaire / Multidisciplinary Theses Server
Still limited in content, but provides access to the full text of mostly French dissertations.
