"As stated on the web site, the Networked Digital Library of Theses and Dissertations Union Catalog is dedicated to 'improving graduate education by developing accessible digital libraries of theses and dissertations.' Because this project is still evolving, there are different interfaces with different coverage. The largest, hosted by OCLC, currently contains records for over 98,000 electronic theses and dissertations from over 40 institutions worldwide. You can search by title, creator, contributor, or abstract and limit by topic, institution, year or language. Records provide abstracts of the work, along with a link to the full text when access is unrestricted. While there is scanty documentation and currently no online help, this project is evolving into a valuable metasearch tool for electronic theses and dissertations residing in disparate institutional repositories"--"Best Free Reference Web Sites 2004."
