The Dramatic Growth of Open Access continues, on both the gold (open access publishing) and green (open access self-archiving) roads. Some noteworthy highlights: PubMedCentral, the world's largest open access archive, noted a significant milestone on June 21: the millionth article....An OAIster search now includes close to 12 million items, an increase of over 4 million items over the past year. The number of repositories continues to increase; OAIster searches include more than 200 more repositories than one year ago. Scientific Commons now includes more than 12 million items, by more than 6 million authors.
The Directory of Open Access Journals lists 2,731 titles, an increase of 439 titles from June 2006, or an average of 1.2 new titles per calendar day. According to Jan Sczepanski on Liblicense, there were over 13,000 open access journals listed on Elektronische Zeitschriftenbibliotek - Electronic Journals Library.
Growth rates of open access archives tracked range from 14% over the past year (arXiv), 33% for rePEC, and 54% for E-LIS and the Canadian Association of Research Libraries (CARL) Metadata Harvester.
The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
I recommend the OA tracking project (OATP) as the best way to stay on top of new OA developments. You can read the OATP feed on a blog-like web page or subscribe to it by RSS, email, or Twitter. You can also help build the feed by tagging new developments you encounter.
