For readers:

Search engines for Open Access documents

  • Google Scholar is already a well-known search engine for academic content. However, it offers few options for narrowing your search. You can conduct more specific and more precise searches, for example by keywords, document types or origin, using the following OA search engines:
  • BASE, a search engine provided by Bielefeld University (search covers more than 25 million datasets), is currently probably the best search engine for Open Access digital content
  • OAIster, search engine provided by the University of Michigan in collaboration with OCLC (search covers more than 18 million datasets)

Of interest for specific disciplines:

  • JURN - specifically for Open Access content in the humanities and social sciences, it is multilingual and produces very good hits, even for non-English content
  • CiteSEERx - specialized for computer science and information sciences


OpenDOAR provides an overview of the many institutional and subject-specific repositories. You can also search by country/region. Webometrics also provides direct links via repository rankings.
