Do textbook authors make much?

[cobrat]

Depends—at many teaching institutions, a textbook totally counts. This is one reason a lot of textbooks are produced by professors at what a lot of CC types think of as “second-tier” institutions—those are the places where the incentives reward writing textbooks.

Interesting.

When I asked my LAC Profs or some Profs at a few LACs ranked above and below my alma mater they mentioned textbooks which didn’t contribute original research/new interpretations to their respective fields/subfields didn’t count for them for tenure/promotion purposes.
