My colleague Rob sent a link out about this new 2-page brief from the Canadian Association of Research Libraries (CARL): Identifying and avoiding predatory publishers: a primer for researchers (pdf).
So-called predatory publishers are those that lack discernible scholarship, academic rigour or credibility. They use aggressive practices to recruit authors and editors. Predatory publishers’ opaque operations and editorial processes are suggestive of an intention to deceive both authors and readers (Butler, 2013).
One of the links in the document points out that Jeffrey Beall maintains a list of Potential, possible, or probable predatory scholarly open-access publishers. I was surprised at how long it was! :-(
