Department meeting today. Folks from our university’s library services gave us a presentation about Open Science. The Q&A leads to the topic of predatory publishers. Interesting to see the institutional differences regarding MDPI journals. Colleagues from other fields/departments do not see these journals as predatory. While it may be a borderline issue, depending on specific fields and journals, the fact that many of these colleagues have consolidated their careers through publications in these venues raised (reasonable) doubts: Do they endorse these journals because they are academically sound, or because their CV has strongly been built on them?
