Vogel G. Quandary: scientists prefer reading over publishing 'open access' papers. ScienceInsider 14 January 2011
The EU-sponsored Study of Open Access Publishing (SOAP Project) surveyed 50,000 researchers for their opinions on open access (OA) journals. The study found two main reasons researchers don't submit their work to OA journals: almost 40% said that a lack of funding for author fees was a deterrent, whereas 30% cited a lack of high-quality OA journals in their field.
Then, scientists love OA papers as readers, but as authors they are still skeptical.
