So, we academics write articles and send them to journals. Other academics who are on the editorial boards may review them for review, or actually review them. Other academics also review the papers.
On the back end, academic libraries complain about the high prices that publishers charge academic libraries for those same journals.
Let's review who pays for the work of those academics in the first paragraph.
- Time spent on research for an article, paid for by: University
- Time spent writing an article, paid for by: University
- Time spent doing whatever the ed board does, paid for by: University
- Time spent reviewing articles, paid for by: University
I am probably missing a few nuances but, usually this kind of behavior is called double billing, and it is frowned upon.
