I have noticed that among biblical scholars, there are many different approaches to publishing. Here are a few I’ve jotted down that are, of course, not mutually exclusive:
Publish or Perish: Publish on, well, everything, regardless of its originality. You have lecture notes and a publisher, after all!
Publish and Progress: Publish on subjects which need further research, challenge, etc., to advance scholarship. (My favorite).
Publish to Précis: Publish broadly in an “overviewish” fashion to keep the sub-disciplines in dialogue.
Publish from Pressure: Publish only when pressed by colleagues, employers, etc. You focus on teaching, right?
Publish from Principle: Publish because a crucial ideology or theology is at stake. It is of supreme or even eternal importance.
I can think of a scholar or two who encapsulates each one well, but I’ll refrain from labeling.
