About Predatory Journals

Predatory journals and publishers are entities that prioritize self-interest at the expense of scholarship and are characterized by false or misleading information, deviation from best editorial and publication practices, a lack of transparency, and/or the use of aggressive and indiscriminate solicitation practices.

Reference → Predatory journals: no definition, no defence, Nature. (December 11, 2019)

The concept of ‘predatory’ journals has many names: fake journals, questionable journals, illegitimate journals, deceptive journals, dark journals, and journals “operating in bad faith”.

Mega journals are open access, peer-reviewed, have a broad subject scope, the research articles are judged by scientific and methodological soundness, which causes the low rejection rate has made the journals growing big, PLoS One (ISSN 1932-6203) was the first mega journal and has been very successful, the publishing model was then imitated by other publishers. 

The perception to mega journals are varied, we suggest DO NOT list mega journal article as your representative or reference publications for faculty promotion nor for application for the national-level research grant.

Self-evaluation Tools

  • The Retraction Watch Hijacked Journal Checker
    Created by the Retraction Watch and Abalkina. This resource is dynamic; more journals will be added as their hijacked status are uncovered.
  • NLM Catalog (for medical journals)
    Where you may confirm whether the journal indexed is in Medline or not. If the record says "Not currently indexed for MEDLINE", it means that the journal may be questionable. 
  • InCites JCR
    Predatory journals often publish fake impact factors, or do not list one at all. You can check a journal title's impact factor via InCites JCR. (Don't forget to connect TMU-VPN when you are off the TMU campus.)
