From: Richard Poynder <[log in to unmask]> Date:, 27 Apr 2015 16:39:18 +0100 Headquartered in Basel, Switzerland, the Multidisciplinary Digital Publishing Institute, or more usually MDPI, is an open access publisher that has had a challenging few years. It has been charged with excessively spamming researchers in order to maximise APC revenue, it has been accused of publishing pseudoscience, and it has been criticised for publishing papers of very poor quality. This has occasionally led to editorial board resignations. The criticism came to a head in February last year, when University of Colorado (Denver) librarian Jeffrey Beall added MDPI to his controversial list of “Potential, possible, or probable predatory scholarly open-access publishers”. Today I have published a Q&A with MDPI, which can be read here: http://poynder.blogspot.co.uk/2015/04/the-open-access-interviews-publisher.html Richard Poynder
