You can find the REA CLEP guides nearly anywhere.. here's a link to one addition of it on Amazon, just do a search on Amazon to see the various versions of this book (just updated every few years)

REA Guides are good overviews on the subject geared towards passing the test, they also include multiple practice tests (which in my opinion are the most important part of the book).

CLEP Subject Guides can be found here

CLEP Subject guides are 50(ish) questions on the subject that are similar in content and structure to the real exam. There's also a very small overview of the sections of the exam.
