Shawns book is the only one I'm aware of.
Linda Woods at PartnerCentric used to have a BUCNH of really good articles on affiliate management. Now with their new site design I can't find that section any more.
The section was called
www.partnercentric.com/pctogo.shtml but now it re-directs to the home page. Here's one of her management articles from her old site:

Wonder if she knows how much of the old good content re-directs to a different page now on the new site? Her old resource section now re-directs to her partner page too. There was some great content, keywords and spiderfood in those sections. I'll ping her and let her know and see if I can get to some of her good articles.
