Friends and implementers of open access around the world: we have outdone ourselves (again!). This quarter a number of initiatives have met or exceeded some interesting milestones. DOAJ is now over 7,000 journals, and still adding more than 4 titles per day. The Electronic Journals Library now lists more than 30,000 titles that are freely available. OpenDOAR now lists more than 2,000 repositories, and the BASE search engine searches more than 31 million documents in repositories. ROARMAP now lists a total of 300 open access mandate policies. Kudos to PMC for clearly posting pertinent data right on their website, and for growing the number of journals making all articles available OA by 19 to a new total of 635 – and for growing free fulltext at the rate of one per minute! Following are links to quick reference and full data versions, rationale and method, items of interest from this quarter, and noteworthy data from this quarter.

Rationale and method
Dramatic Growth of Open Access Series
Items of interest since June 30, 2011
- Walters, W. H., & Linville, A. C. (2001). Characteristics of open access journals in six subject areas. College and Research Libraries, 72(4), 372-392. Retrieved from http://crl.acrl.org.proxy.lib.sfu.ca/content/72/4/372.abstract. Good analysis of English-language DOAJ journals. Understates growth of OA, based on an article by Sally Morris. See here for critique of this approach.
- Bhaskar Mukherjee and Mohammad Nazim have published “Open Access Institutional Archives: A Quantitative Study (2006-2010)” in the DESIDOC Journal of Library & Information Technology.. Link to Charles Bailey’s Digital Koans excerpt rather than article per se as I am not able to connect to the journal today.
