From a LIBER Blog Post:
The DART-Europe E-theses Portal, hosted by UCL Library Services in association with LIBER, is a metadata aggregation that aims to provide one-stop access to Europe’s open access research-level theses. DART-Europe now gives access to over 300,000 full-text research theses from 424 Universities in 23 European countries. The 300,000th thesis to be aggregated was this one, awarded by the Université de Technologie de Belfort-Montbeliard and supplied by STAR (Dépôt légal des thèses électroniques Françaises), DART-Europe’s partners in France.
The Portal offers simple search and browse facilities. Searches can be filtered by University, author, source, country, date and language.
