I have been recommending this book to people I know since I first encountered the first edition. This second edition is expanded and revised, and is even more helpful to Call of Cthulhu gamers, keepers, and especially writers of Mythos fiction. I've been using it as source material for my own odd little tales since I began writing them. And while it is true that the author has been known to frequent some of the same newsgroups that I do, he did not pay me to say these things. The book is extensively indexed and cross-referenced, with a very helpful timeline of the Cthulhu Mythos toward the back. It is clearly written, has doses of the author's dry sense of humor, especially in his choice of a quote for the preface page, is quite attractively packaged, and will look very nice on your bookshelf next to the many volumes of HP Lovecraft that you should have if you're reading this.
