ProQuest Dissertations and Theses


ProQuest Dissertations and Theses is an online database that indexes, abstracts, and provides full-text access to dissertations and theses. The database includes over 2.4 million records and covers 1637 to the present. It is produced by ProQuest and was formerly known as ProQuest Digital Dissertations. The bibliographic database is known as Dissertations Abstracts or Dissertations Abstracts International.
PQDT annually publishes more than 90% of all dissertations submitted from accredited institutions of higher learning in North America as well as from colleges and universities in Europe and Asia. Over the past 60 years, PQDT has amassed more than 1.4 million titles beginning with the first U.S. dissertation accepted by a university in 1861. ProQuest began digitizing dissertations in 1997 from a microform archive.
In October 2015, ProQuest added the ability for authors to include an ORCID identifier when submitting a thesis.
