A Confusion of Journals - What Is PubMed Now? - The Scholarly Kitchen

"Now, a new twist is emerging, and that seems to be that PubMed may be consciously or unwittingly acting as a facilitator of predatory or unscrupulous publishing.

In a paper published in Neuroscience, the authors analyzing the neurology and neuroscience journals included in PubMed found that:

• Twenty-five predatory neurology journals were indexed in PubMed, accounting for 24.7% of all predatory neurology journals.
• Fourteen predatory neuroscience journals were indexed in PubMed, accounting for 16.1% of all predatory neuroscience journals.
• Only one of the 188 predatory neuroscience or neurology journals appeared in the DOAJ index.
• Only 54.6% of the journals deemed predatory in neuroscience actually contained articles."
