Some final thoughts on blurbs and logrolling. A reader writes: "One should neither blurb nor review the work of one's own student; the logrolling is all too evident, and blurbs should be accepted for what they are: endorsements by people who are disposed in favor of the author. At times I've refused to blurb, and that's created an uproar; I've also blurbed a book when I did not agree with all the author had said ... because I thought the arguments were worthy of a hearing."
Those are certainly policies that will serve readers well.
