Some weeks ago I was asking about a good Photoshop 7 book. On a recent trip to the UK, I looked at dozens of books on this subject, but the one that stood out above all the others (in my opinion anyway) was "Teach Yourself Visually Photoshop 7". As the title suggests, lots and lots of pictures with full colour screen shots, and lots of tips and tricks and so easy to learn, over 300 pages and it doesn't skimp on anything. A great book highly recommended. Also available for other photoshop programs.
