The first quarter of the Dramatic Growth of Open Access is now available:

http://poeticeconomics.blogspot.ca/2014/04/dramatic-growth-of-open-access-first.html

Highlights: featured are three open access initiatives with
particularly strong growth this quarter, the Directory of Open Access
Books, Highwire Press' free sites, and PubMedCentral (with 5 of the
top 15 indicates by percentage of growth). PMC growth indicators
include a 20% annual growth rate (5% this quarter alone) in the number
of journals actively participating in PMC, now up to 1,769 journals.

Note that DOAJ titles have decreased this quarter due to a vigorous
weeding process at DOAJ. While the number of journal titles in DOAJ
has decreased, the total number of articles searchable at an article
level has increased by more than 20 thousand articles in this time
frame.

The downloadable data versions are now available in the Scholar's
Portal Dataverse (thanks to University of Ottawa Library), along with
the most recent version of the Rationale & Method. If you use this
