I just took this test about a week ago. What I used to prepare for it was the REA guide to Analyzing and Interpreting Literature. The ISBN # is 0-87891-897-3. You should be able to find it on Amazon.com: Online Shopping for Electronics, Apparel, Computers, Books, DVDs & more or Half.com. In particular I found doing the practice tests to be the most help. The book itself is a good overview but actually analyzing the passages made the biggest difference for me. I'd definitely recommend the book.
