Shen C, Bjork B. "Predatory" open access: a longitudinal study of article volumes and market characteristics. BMC Medicine 2015;13:230
The so-called predatory publishers are causing unfounded negative publicity for open access publishing in general. The authors of this article used a multistage stratified sampling method to take a look into the predatory publishers and journals on Beall’s list and generated their development trend over time. They found that the problems caused by predatory journals are limited to just a few countries, where the academic evaluation practices strongly favor international publication, but without further quality checks.They believe that the publishing volumes in such journals will cease growing in the near future.
