Game Publishing Lessons is a collection of articles about publishing your own games, some from the RPGGeek community, and some from the author.

I equate this book with having the opportunity to sit down with someone who's gone through the process and being able to ask them all sorts of questions, and Jacob Wood does a good job of anticipating the sort of information a would-be publisher will need to know.

Some of the information won't be evergreen (specifically info on publishing software and some web resources), but if you're looking to publish a game and you don't know some who has (so you can bend his or her ear for an hour) this book is a good start.
