"The World’s Approach towards Publishing in Springer and Elsevier’s APC-Funded Open Access Journals "
College & Research Libraries has released an e-print of "The World's Approach towards Publishing in Springer and Elsevier's APC-Funded Open Access Journals.
Here's an excerpt:
The Netherlands, Norway and Poland ranked highest in terms of their OA shares. This can be attributed to the financial resources allocated to publication in general, and publishing in OA journals, in particular, by the countries. All developed countries and a large number of scientifically lagging and developing nations were found to publish OA articles in the APC journals. The OA papers have been exponentially growing across all the country scientific groups annually. Although the advanced nations published the lion share of the OA-APC papers and exhibited the highest growth, the under-development groups have been displaying high OA growth rates.
