Very interesting casehttp://science.sciencemag.org/content/354/6308/23.full There are many predatory publishers out there, and beware of them. Hope Librarians can make the research community aware about the pitfalls of OA publishing and stop misusing this great idea. Often young researchers and graduate students fall in to the traps, sometimes faculty too.  ---------- Dr. J. K. VIJAYAKUMAR,
