ProQuest Dissertations and Theses (PQDT) is a powerful tool for researching unpublished, academic resources. The official digital dissertations archive for the Library fo Congress, PQDT is a collection of citations to dissertations and theses worldwide from 1861 to the present day. Full-text is available for most of the dissertations added since 1997 and some of the older graduate works. It also includes citations to British and Irish dissertations and theses (PQDT: UK & Ireland) since 1761 and abstracts for content since 1986. 

ProQuest permits multiple search methods, including by author and title, but also by institution, subject, language, and even advisor. By selecting “Browse” rather than basic or advanced search, users can find dissertations either by subject or location. 

PQDT Global adds more than 300,000 full text dissertations each year and has metadata without full text for other items. For titles not available in ProQuest, ProQuest offers retrieval from partner institutions for a fee. The University Library also has a guide to finding dissertations and theses.
