I'm a nobody, but consider making the pages less clicky and more product page-y, with the external references that provide the structure of your site constituting something of a "topics covered in this book." I think the references/links should be at least as prominent as the book blurb that currently serves to authoritatively describe the contents. My point is that the contents may actually be described (for sufficient numbers of refs) better by listing how people are actually recommending it, how its readers are using it. You could even implement a semantic parser that constructs a new book blurb based on the words and sentences in the recommendations and references. :) Anyway, good luck!
