Pepperdine University Libraries now provide access to American Doctoral Dissertations 1933-1955 database, which contains digitized content from the print index Doctoral Dissertations Accepted by American Universities (DDAAU). The database includes nearly 100,000 indexed dissertations from 1933 through 1955.
American Doctoral Dissertations 1933-1955 is unique as it represents an extensive record of dissertations accepted by American universities during this time period. This print index was compiled annually by the H.W. Wilson Company for the National Research Council and The American Council of Learned Societies by the Association of Research Libraries. EBSCO Information Services (EBSCO) collaborated with the Congregational Library & Archives in Boston to digitize the print indexes originally published by the H.W. Wilson Company with the support of a donation from the H.W. Wilson Foundation.
