Let the Competitio​n Begin! Dramatic Growth of Open Access 6/30/11

The June 30, 2011 issue of The Dramatic Growth of Open Access is now available, at: http://poeticeconomics.blogspot.com/2011/06/let-competition-begin-dramatic-growth.html

Highlights:

Celebrates the growth of open access in the area of the medical literature.  It was only a little more than a decade ago when the medline index was available only to subscribers.  Today, not only is PubMed available to all – so are more than 3.3 million free fulltext documents indexed in PubMed. 1,176 journals voluntarily participate in PubMed; on average, one new title is added per day.  More than half of these journals are open access.

COMPETITION YEARS HYPOTHESIS

Builds on the finding of Laakso et al of a tenfold increase in open access publishing from 1993 to 2009 (http://www.plosone.org/article/info:doi/10.1371/journal.pone.0020961). Laakso et al theorized a threefold division during this time frame, the pioneering years, the innovation years, and the consolidation years. My hypothesis, based in part on the announcements in recent months by traditional publishers appearing to enter into serious competition in the OA arena (Springer Open – now with 50 journals; Wiley Open; Nature Communications, and today, Open Biology), is that we have already entered a new phase, which I am calling the competition years.
