Dramatic Growth of Open Access By the Numbers

From Heather G. Morrison, Simon Fraser University School of Communication

VanCouver, British Columbia, CA 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 (Directory of Open Access Journals) 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 (Directory of Open Access Repositories) now lists more than 2,000 repositories, and the BASE search engine searches more than 31 million documents in repositories. ROARMAP (Registry of Open Access Repositories Mandatory Archiving Policies) now lists a total of 300 open access mandate policies. Kudos to PMC (PubMed Central) 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.
