I tried to get some of the members here to help me out with this same question when I started showing up here, and got no response. Here is a book review of sorts on Mr. Phillips 5th edition from some of the members.

If your wondering about which books are useful, use the search icon in this forum, using the authors name. You'll be amazed at what is actually available that's hidden here and there. It will require some effort on your part but a lot of book reviews are here already.
Of the books on lock picking available that I've read, only one word comes to mind...."asserific". Do yourself a favour and use the money for decent tools. The MIT guide is the as good a reference as any, and it's free. All the books I've read so far, only rehash what was said in "The Guide".
As for info on picking advanced locks, everything you'll need is here. Pick the simple stuff first. Make decent posts and when you think your ready ask for entry into the advanced sections. I haven't even tried to gain entry into the advanced forum yet. All the locks I have access too were covered in the regular forum. If I ever get an Abloy, Medeco, or ASSA I may ask for entry, but for now, where I am is more than adequate. Have fun and keep on picking!
