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

[Stevan Harnad <amsciforum@gmail.com>]

Journal articles that are OA, as a percentage of annual journal 
articles published is of course not the same as the percentage of 
annual journal articles that are published in OA journals (Gold 
OA). There's also the percentage of annual journal articles that 
are published in non-OA journals but made OA through author 
self-archiving (Green OA). The latter percentage is about 15% and 
growing, especially because Green OA self-archiving can be, and 
is being, mandated by their authors' institutions and funders.
