Many academics have to find the money to publish books from grants. This is a job on top of a job and they earn no royalties on anything.
Greetings, Psst, most academics aren't making much money from their book publications. They can't use their royalties. This means we are not popping our collars and purchasing prosecco or NA prosecco. The few scholars who are making bank are not publishing with university/academic presses.
