In June 2017, Jeffrey Beall published an opinion piece in  Biochemia Medica  titled “What I Learned from Predatory Publishers.” 1  While there are several elements of this publication that I find inaccurate or problematic, I’m choosing four specific themes within his piece to critique. In the interest of full disclosure, I am Jeffrey Beall’s direct supervisor at the University of Colorado-Denver’s Auraria Library and have been since I began working there in July 2015.
