OpenDissertations is an open-access database built to assist researchers in locating both historic and contemporary dissertations and theses. Created with the generous support of the H.W. Wilson Foundation and the Congregational Library & Archives in Boston, it incorporates EBSCO’s previously released American Doctoral Dissertations, and features additional dissertation metadata contributed by select colleges and universities from around the world. Providing researchers with citations to graduate research across a span of time, from the early 20th century to the present, this database will continue to grow.

Provides full-text of ORU dissertations and theses published after 1996; includes D.Min. research projects only prior to 1996; contains indexing since 1978.
