RE: Dramatic Growth of Open Access - March 31, 2009

[<Toby.GREEN@oecd.org>]

A dramatic growth in OA journal titles is one thing, but surely 
what counts is the number of OA articles as a percentage of all 
articles. Last week at UKSG, Derk Haank of Springer estimated 
that about 5-7% of newly published articles were OA today and he 
expected growth to be modest. He also reckoned that OA's share of 
all newly published articles would stabilize at about 10%. Does 
anyone have any figures on the share of OA articles as a 
percentage of all articles to corroborate or challenge Derk's 
estimates?

The dramatic growth is also confirmed by Evalinde Hutzler in
figures published in the german journal Bibliotheksdienst on page
170. Maybe she is also an "avowed advocate" but the German
figures are in line with the development in DOAJ.

In 2002 there were 9.574 red titles and 3.161 green titles and in
2007 18.314 red ones and 16.492 green ones. That is a 100% red
growth and a 500% green growth.

My guess is that in 2009 there are more free open access journals
than commercial.

Without doubt, in the long run, open access will dominate
publishing.
