Many publishers are still deciding how to deal with the issue of open access. Rarely do they have their policies clearly stated. A group called Sherpa (Securing a Hybrid Environment for Research Preservation and Access), funded by JISC (Joint Information Systems Committee) and CURL (Consortium of Research Libraries in the British Isles), is an independent group that investigates issues in the future of scholarly communication and publishing. They have a searchable archive with summaries of permissions that are normally given as part of each publisher's copyright transfer agreement. The information for the archive is based on the publishers' listings produced by the ROMEO project. ROMEO uses a color scale to indicate levels of permissions:
white -- archiving not formally supported
yellow -- can archive pre-print (ie pre-refereeing)
blue -- can archive post-print (ie final draft post-refereeing)
green -- can archive pre-print and post-print
