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. PQDT is also the official digital dissertations archive for the Library of Congress. Also included are the citations to British and Irish dissertations and theses (PQDT: UK & Ireland) since 1761 and abstracts for content since 1986.
Note: UIUC masters theses are not in PQDT. They are only found in IDEALS or in the library catalog.
