arXiv® is a curated research-sharing platform open to anyone. As a pioneer in digital open access, arXiv.org now hosts more than two million scholarly articles in eight subject areas, curated by our strong community of volunteer moderators. arXiv offers researchers a broad range of services: article submission, compilation, production, retrieval, search and discovery, web distribution for human readers, and API access for machines, together with content curation and preservation. Our emphasis on openness, collaboration, and scholarship provide the strong foundation on which arXiv thrives.

Access to 1,219,730 open access research theses from 578 Universities in 29 European countries.

The DART-Europe E-theses Portal is a searchable database of electronic research theses held in European repositories. The theses listed are open access – publicly available, in full, without charge.

The DART-Europe Portal does not store theses, but the database aims to provide a link to at least one electronic copy of every thesis listed in the database. DART-Europe holds as much information as possible about each thesis, but this can vary, depending on the source of the information. As a minimum, details of the author, title and date of award are held.

DART-Europe was founded in 2005 as a partnership of national and university libraries and consortia to improve global access to European research theses. The DART-Europe E-theses Portal is managed by UCL Library Services.
