*** Apologies for cross posting ***
New charts published on the SHERPA/RoMEO Blog show that 87% of journals allow some form of immediate self-archiving of articles, although in only 60% of cases is this a post-peer-reviewed version.

This rises impressively once embargo periods have expired and any other restrictions have been complied with, showing that 94% of journals permit peer-reviewed articles to be archived. Furthermore, nearly a quarter of journals allow the publisher's version/PDF to be archived. Only 5% of journals do not permit any form of archiving.
The statistics were compiled from a snapshot of the RoMEO Journals database taken on the 15th Nov.2011, when it contained about 19,000 titles.
