American Doctoral Dissertations

American Doctoral Dissertations has been expanded to offer greater coverage of 20th century research as well as access to full text.

Initially, this free research database provided access to the only comprehensive record of dissertations accepted by American universities between 1933 and 1955, the print index Doctoral Dissertations Accepted by American Universities.

The newly enhanced database includes more than 153,000 theses and dissertations in total, including 70,000 new citations for theses and dissertations from 1902 to the present.

The new citations include a link to access the full text, when available, via the Institutional Repository where the thesis or dissertation is housed, such as OhioLINK, Rochester Institute of Technology and North Carolina State University.
