In a terrific albeit not cheerful essay about book publishing today, former Random House exec Daniel Menaker, in Redactor Agonistes, talks about insecurity and unhappiness in the book biz, but also explains why and how it has changed so much, and that, after decades of only getting bigger, it is now shrinking. This essay appears in Barnes & Noble's Review, which in addition to reviews and essays has some interesting dialogues with authors.
