I have seen the "Getting Started with Arduino" book on the shelves at Radio Shack. It is also available from MakerShed
or you can download the pdf from:
http://quarknet.fnal.gov/fnal-uc/quarknet-summer-research/QNET2011/project_files/teacher_files/Getting_Started_with_Arduino.pdf
and print it yourself.
I'm pretty sure I have seen the larger book (I think it is the one you are after, 170 pages or so) at Radio Shack as well.
