With more than 2.9 million entries, ProQuest Dissertations & Theses (PQDT) is the most comprehensive collection of dissertations and theses in the world.

ProQuest Dissertations & Theses allows:

• Graduate students to consult the database to make sure their proposed thesis or dissertation topics have not already been written about
• Students, faculty, and other researchers to search for titles related to their scholarly interests
• Instant access to high-quality, peer-reviewed and multidisciplinary research materials
• Building your ebooks collection – with each dissertation including an ISBN, ProQuest is the world’s largest publisher of ISBNs
• Cross-searching with journal and other content types on the ProQuest platform

The database includes bibliographic citations for materials ranging from the first U.S. dissertation, accepted in 1861 as well as European dissertations back from the 17^th century, to those accepted as recently as last semester.

ProQuest Dissertations & Theses is the official dissertations repository for the Library of Congress and the publishing partner of the National Library of Canada.

PQDT offers access to the first 10% of the dissertation (up to 24 pages) for those dissertations and theses available in electronic form.

PQDT is updated weekly and features 24 indexed and searchable fields, including full text searchability.
