The Networked Digital Library of Theses and Dissertations (NDLTD) is an international organization dedicated to promoting the adoption, creation, use, dissemination and preservation of electronic analogues to the traditional paper-based theses and dissertations.

The Institute of Historical Research has been collecting information about history PhDs and research Masters since the 1930s. You can now browse or search the directory of theses completed from 1970 onwards, as well as current research in progress.

The DITED service is suspended for this reason and while the service is being redefined it is suggested to deposit theses in paper and CD-ROM with the Division of the National Bibliographic Agency and Acquisitions (This email address is being protected from spambots.
