4. www.uni-stuttgart.de 29.11.2007Frank Scholze The current situation for digital repositories  More than 1000 institutional repositories worldwide, about 120 in Germany  Many others: disciplinary, national, …  Many types: Primary data, textual documents, learning materials, multimedia objects, code …  Documents: incl. pre-prints, postprints, technical papers, dissertations, theses …  Various repository software

5. www.uni-stuttgart.de 29.11.2007Frank Scholze  Many have the OAI-PMH implemented  small but relevant local specialties  Some international registries exist  OpenDOAR, ROAR …  Some national registries exist  DINI list …  Some search engines exist  BASE, OAIster, Google Scholar … What is known about repositories?

6. www.uni-stuttgart.de 29.11.2007Frank Scholze Collaboration in repositories  Very few mature national repository organizations/collaborations  SURF, DINI …  No trans-national repository organization/collaboration  Lack of data harmonization, orchestration of services

7. www.uni-stuttgart.de 29.11.2007Frank Scholze From the user point of view [ talking about researchers ]  Fragmented, obscure information landscape  content can be (partly) searched and found  quality and re-use differs from repository to repository
