Publishers challenged over access to papers.

Reports that a group of researchers say they will stop buying, publishing, or reviewing for any scientific journal that refuses to place its research papers in a proposed online database, Public Library of Science, within six months of initial publication. Reaction of publishers, who claim that free access will leave journals without enough revenue to support peer review; Speculation that the research will end up on the publicly-funded PubMedCentral rather than on a private site.
