Compiled by Stuart Lewis, University of Wales Aberystwyth, from repository lists offered by ROAR and OpenDOAR.
OpenDOAR - the Directory of Open Access Repositories
Funded in part by SPARC Europe
OpenDOAR is an authoritative directory of academic open access repositories. As well as providing a simple repository list, OpenDOAR lets you search for repositories or search repository contents. They provide tools and support to both repository administrators and service providers in sharing best practice and providing tools to improve the quality of the repository infrastructure.
Experimental OAI Registry
The Grainger Engineering Library at University of Illinois at Urbana-Champaign has collected Identify, ListSets, ListMetadataFormats, and sample records from a compendium of OAI compliant repositories, added the data to a database, indexed them, and made them searchable.
Institutional Archives Registry
Tim Brody of Southampton University has created a web site that lists and dynamically graphs the amount of content of archives that:
(1) run GNU EPrints software, and/or
(2) archive open access research articles.
Core Metalist of Open Access Eprint Archives
Produced by Steve Hitchcock, Southampton University, U.K. This list and its categorization gives a broad overview of the structure, size and progress of full-text open access eprint archives.
List of Open-access Archive Lists
Maintained by Peter Suber, Earlham College, Indiana. This list captures the most comprehensive lists available.
Computing Research Repository (CoRR)
Through partnerships, the Association of Computing Machinery established this disciplinary repository in 1998. Based on an open protocol, the repository represents author's submitted papers in 35 subdisciplines. Authors submit their documents which are included in CORR via an automated process; thus, the papers are not refereed.
arXiv.org e-Print archive
ArXiv is an e-print service that hosts multiple disciplinary repositories, in the fields of physics, mathematics, non-linear science, computer science, and quantitative biology. Originally based at the Los Alamos National Laboratory, arXiv is owned, operated and funded by Cornell University.
