Doctoral dissertations and master's theses are rich information resources. They generally provide a comprehensive literature review and extensive bibliography for the topic, as well as original research. In the past, they have been very difficult to obtain, but many are now readily available through various databases and repositories.
By far the most important database for locating dissertations is ProQuest Dissertations & Theses Full Text. This provides citations and abstracts to more than 2 million dissertations and masters theses in all fields from 1861 to the present. The full text of most dissertations are also available for download.
