[GOAL] Dramatic Growth of Open Access March 31, 2013

[Heather Morrison]

The March 31, 2013 issue of Dramatic Growth of Open Access is now  
available.

Highlights

This issue features a comparison of open access growth including CC-BY  
article growth figures supplied by OASPA. In brief: for every CC-BY  
article addition tracked by OASPA, repositories around the world add  
359 documents as found by a BASE search, DOAJ adds 10 articles that  
are not CC-BY licensed (90% of DOAJ article growth), arXiv and SSRN  
each add 3 documents, and the Internet Archive adds lots of texts,  
movies, sound recordings and concerts.  Recent research suggests that  
CC-BY is the preference of a small minority of scholars.

The top 10 growth figures by percentage for both this quarter and the  
past year are presented. Looking at percentage growth brings out  
substantial growth in initiatives with smaller numbers. Note that  
smaller numbers are not necessarily less significant. One open access  
funding agency mandate can mean free access to tens or even hundreds  
of thousands of articles, for example. Open access mandates are high  
on the list of percentage growth figures, including 26 funding agency  
OA mandates this quarter for a total of 80 and a growth rate of 48%.  
The Directory of Open Access Books is growing up leaps and bounds, or  
to be more specific added 13 publishers and 135 books this quarter.  
The usual suspects (Directory of Open Access Journals, PubMedCentral,  
and BASE) continue to rank highly on percentage comparisons. Highwire  
Press added a total of 20 totally free sites this past year for a  
total of 71, an impressive sixth place (not bad for an initiative that  
isn't focused on open access).

Kudos to DOAJ for hitting the 1 million article milestone. Bjork,  
Laakso, Welling and Paetau have issued a preprint of another major  
open access growth study, the Anatomy of Green Open Access, finding  
that the coverage of all journals articles as green open access is  
currently at 12%. Suber has posted additional figures and analysis and  
updated the open access by the numbers section of the Open Access  
Directory. New this issue is the amazing 281 billion web pages of the  
Internet Archive.
