References on DNA testing, and related topics

I've recently read a couple of books on genetic testing, and related topics. While they do not answer all my questions, they seem to be pretty reasonable:

(1) Trace Your Roots with DNA by Megan Smolenyak Smolenyak (this is her name and not a typo) and Ann Turner.

Copyright 2004, so perhaps a little dated, but still a reasonable discussion of what DNA testing can do.

Still in print @ $16.95

(2) The Journey of Man: A Genetic Odyssey by Spencer Wells

Copyright 2002, also perhaps a little dated.

Spencer Wells is the person involved with the Genographics Project (National Geographic). This book is about population migration, more of a "deep ancestry" approach. It would be useful to read this and watch the National Geographic video (watch the video first).

Still in print at $14.95.

I ordered both of them from an online bookstore, none of the brick & mortar stores had them.

I'm still looking for something that does an in-depth description of haplo types.
