Get a suspicious invitation to publish? Find a new journal and want to know if it meets your quality standards? We developed this checklist to help potential authors determine whether a journal or publisher is potentially predatory or of low quality. You should not use only one item from this checklist to pass judgment; for example, new publishers and journals don't have many articles or books published, but may otherwise be high quality. Look at all the factors, and please call or email if you would like assistance.
