This document discusses how to identify and avoid "predatory journals" that charge publication fees but provide minimal peer review services. It provides guidance from Tufts University, the British Medical Journal, and the London School of Hygiene & Tropical Medicine on evaluating journals. Key recommendations include checking if a journal is listed on the Directory of Open Access Journals or indexed in databases, whether the publisher belongs to organizations like OASPA that promote standards, and ensuring the editorial board consists of recognizable experts in the field. Visitors to a journal's website should look for signs of professionalism and transparency regarding practices and fees.
