OpenDissertations.org, a project from EBSCO Information Services (EBSCO) and BiblioLabs, has now been officially been launched. It lists more than 800,000 Electronic Theses and Dissertations (ETD). It includes any electronic theses listed in the British Library’s EThOS Service as well as material listed in American doctoral theses and masters theses. Search by author, keyword and date. There are links through to catalogue records where the facility to download is often available.
Another well recommended theses online catalogue search is NDLTD, the Networked Digital Library of Theses and Dissertations. NDLTD provides information and a search engine for electronic theses and dissertations (ETDs), whether they are open access or not. It also has detailed information on projects for digitisation worldwide.
