There are a lot of problems with Kammen's book.
Here is an old thread that talks about it.
If you're looking for something aside from 7CSFAP, there is Othmer's book (the expanded version called "Seven Card Stud Poker"). It's not 7CSFAP, but I think it's certainly worth reading. Andy B. will disagree, as I'm sure others will. A lot of the charts and diagrams just seem to take up space, but there is useful information scattered about.
Mike from Professional Poker pimped it to me. Turns out that he's actually the only person selling it on Amazon, go figure, but I think it's worth reading.
Then of course there's the simple-but-readable West book, which is a little light if you're don't feel like digging into 7CSFAP right off. Other than the Reese chapter, it's what I read first.
