Electronic Theses and Dissertations (ETDs) in the Humanities (Univ. of Virginia, USA)

Directory of Electronic Theses and Dissertations currently in progress.

This site serves as a clearing-house for online information related to electronic theses and dissertations (ETDs) in the humanities. The site's most important feature is a directory of most (maybe not quite all) of the ETDs that are currently in progress in the various disciplines that comprise the academic humanities. Among its other uses, I hope the material available here will be of aid to graduate students who are faced with securing approval and support for an ETD of their own. Audiences also include faculty who want to make informed decisions about supervising an ETD, as well as librarians, administrators, and academic publishers.

Indexes to and Bibliographies of Dissertations (Yale University, USA)

Dissertation abstracts online combines, enhances and enlarges the indexing access to records of dissertations included in its printed predecessors, Dissertation abstracts international (DAI) and Comprehensive dissertation index (CDI) . Unlike DAI, abstracts are included only for titles completed since July 1980, although like CDI, bibliographic data for titles is included for dissertations back to 1861. It also includes citations and abstracts for masters theses drawn from University Microfilms' Masters Abstracts International.

Dissertation Abstracts International

Dissertation Abstracts International on CD-ROM includes abstracts of doctoral dissertations submitted to the publishers by 550 participating institutions in North America and throughout the world. Each author- prepared abstract, up to 350 words in length, describes in detail the original research project on which the dissertation is based.

The CD-ROM lists dissertations from 1861 to the present, although abstracts are not available electronically for pre-1982 dissertations. Earlier abstracts are in printed volumes that must be fetched for you from the Stack. The CD-ROM is updated
