Best Practices - Spotting Predatory Journals - Predatory Conferences - Link to Archived "Beall's List" --- Dalhousie University Libraries
Predatory Journals: "Predatory journals are pseudo-academic journals that exist for the sole purpose of collecting fees from authors. They have emerged to exploit the Open Access publishing business model whereby authors pay a fee to make their work freely available to the public. Predatory journals are a concern because they are sometimes difficult to identify. They pose as high quality Open Access journals but fail to deliver meaningful editorial and peer review."
Predatory Conferences: "Predatory or scam conferences charge a fee that allows the organizers to realize a substantial profit. They often take place in an appealing travel destination and may promise publication (which is inconsistent with rigorous peer review). Such conferences are not well organized around a theme or field to facilitate productive interactions and lack the benefits described above. "
Identifying Deceptive Publishers: A Checklist - University of Toronto Libraries
"Deceptive publishers (also commonly referred to as 'predatory journals') are for-profit entities that purport to publish high quality academic research, but who do not follow accepted scholarly publishing best practices. Their ultimate goal is to make money, not publish quality research. A deceptive publisher may acquire the copyright to your research but never publish. A deceptive publisher may publish your work, but then disappear, resulting in there being no public record of your published article."
