Instructions: first, find the journal's publisher - it is usually written at the bottom of journal's webpage or in the "About" section. Then simply enter the publisher's name or its URL in the search box above. If the journal does not have a publisher use the Standalone Journals list.
Original list
This is an archived version of the Beall's list - a list of potential predatory publishers created by a librarian Jeffrey Beall. We will only update links and add notes to this list. A list of new predatory publishers is available below the original one.
Frontiers (note: details of how this publisher was added to the list: here; received claims from multiple academics <verified their academic email addresses> about misconduct during the publication process of a substantial amount of Frontiers journals; some of them have not been removed from editorial boards of Frontiers journals despite their requests)
Multidisciplinary Digital Publishing Institute (MDPI) (note: MDPI is very much a hit-and-miss. Some of their journals have a very poor peer-review; some are fine. In the future, I will list MDPI journals separately.)
This is a list of questionable, scholarly open-access publishers. We recommend that scholars read the available reviews, assessments and descriptions provided here, and then decide for themselves whether they want to submit articles, serve as editors or on editorial boards. In a few cases, non-open access publishers whose practices match those of predatory publishers have been added to the list as well. The criteria for determining predatory publishers are here.
We hope that tenure and promotion committees can also decide for themselves how importantly or not to rate articles published in these journals in the context of their own institutional standards and/or geocultural locus. We emphasize that journal publishers and journals change in their business and editorial practices over time. This list is kept up-to-date to the best extent possible but may not reflect sudden, unreported, or unknown enhancements.
