Sherpa/RoMEO: Publisher copyright policies & self archiving
(SHERPA. Securing a Hybrid Environment for Research Preservation and Access)
This site, based in the UK, is designed to assist authors in managing their rights by categorizing rights in a standard format. Authors can  view summaries of publishers' copyright policies in relation to self-archiving, check to see if publisher policies comply with funding regulations, and search journal and publisher information by Journal Title, Publisher Name and ISSN. Not all publishers are represented and not all records are up-to-date, but this is a good place to find out which publishers follow "open access" policies more closely.
