So I had a super quick look into this out of curiosity. My first question is - where are you expecting to be able to retrieve the book metadata from? CrossRef.org seem to have it (and can supply it in xml format) but you have to become a "Basic Affiliate" with an annual fee of $2000 from my reading of their website. Is there another source of journal metadata that is free?
