The aim of ROAR is to promote the development of open access by providing timely information about the growth and status of repositories throughout the world. Open access to research maximises research access and thereby also research impact, making research more productive and effective.
This is a list of OA disciplinary respositories (also called central or subject repositories). Unless otherwise noted, they accept relevant deposits regardless of the author's institutional affiliation.
An Eprint Archive is a collection of digital documents. OAI-compliant Eprint Archives share the same metadata, making their contents interoperable with one another. Their metadata can then be harvested into global "virtual" archives, such as OAIster, that are seamlessly navigable by any user (just as a commercial index or abstract database is navigable, but with full-text access).
