Hello, have any other mentors been asked to check textbooks and, if so, what have been your experiences/responses? I've recently had a request along these lines (proofing/editing/fact checking) and I'm torn between wanting to help and it being much too big a job and out of my realm of expertise. I'd really like to direct my mentee to somebody who could help rather than just say 'no' but I'm not sure where to start. I believe that his intention is to self-publish. Does anybody have any advice? Thank you.
