With more than 3.1 million citation records, the ProQuest Dissertations & Theses (PQDT) database is the world's most comprehensive collection of dissertations and theses. No other collection can offer the depth that PQDT does. ProQuest has the full text of 2.1 million dissertations and theses in our vaults, and over 1.6 million of them are available online in PDF format. In addition to the full text in PDF format, PQDT offers access to 24 page previews for those dissertations and theses available in electronic form.
PQDT represents the work of authors from over 1,000 graduate schools and universities, and we publish around 70,000 dissertations and theses each year. It includes bibliographic citations for materials ranging from the first U.S. dissertation, accepted in 1861, to those accepted as recently as last semester. Citations for dissertations published from 1980 forward also include 350-word abstracts written by the author. Citations for master's theses from 1988 forward include 150-word abstracts.
