The story
Libertas Academica is a publisher of open access ("OA") scientific, technical and medical journals. It is privately funded and was founded specifically to publish OA journals. It was established in late 2004 with the launch of two journals, Evolutionary Bioinformatics and Cancer Informatics. Additional journals have been published since. It was included on a list of "predatory" open access publishers in 2010 but later removed. In 2013, a sham study reporting that a compound isolated from lichen can kill cancer cells was submitted to one of the journals published by Libertas for peer review. After review, the sham study was correctly rejected for publication.
