Paperback Confidential -- Brian Ritt

If you're at all interested in old paperbacks, you're going to want this book.  It's a wonderful survey of authors who wrote the crime fiction that makes finding that out-of-print book so much fun.  I only wish I'd had a copy of this to take with me when I was combing through used-book emporiums back in the long ago.  Ritt gives biographical sketches of many, many writers, both well known and obscure, and he even includes a "PseudoDex" that gives you the pen names that many of them used.  Each sketch ends with a selection of titles, but these lists aren't complete.  They're a great start, though.  I don't know about every reader of this blog, but there must be a lot of you who are the target audience for this one.  Check it out.
