The Dramatic Growth of Open Access Series is a quarterly series (end of March, June, September, and December) of key data illustrating the growth of open access, with additional comments and analysis. The series is available in open data and blogpost (commentary) editions. The quarterly series began December 31, 2005, and is predated by a peer-reviewed journal article featuring data as of February 2005.

The September 2010 edition of the Dramatic Growth of Open Access is now available.


DOAJ is now at 5,452 titles, and is adding 3 titles per day A BASE search of repositories worldwide encompasses more than 25 million items, growing at 8,000 documents per day 960 journals are voluntarily participating in PubMedCentral; the growth rate is about a title per day.

This issue asks the deliberately evocative question of whether we can now, or soon will be able to, compare open access with subscription resources on a numerical basis.  For example, there are now at least four free or open access journal collections with more than twice the number of titles of the world's largest
commercial publisher.
