I am working on a module that can query isbnreference.org for information about a particular book.
have you thought about working with Ed Summers to put that into Business::ISBN ?
I have joined the isbnsearch-devel list that maintains the software for isbnreference and have brought up the idea on that list.
I don't think it's appropriate to merge with Business::ISBN, which just deals with ISBN data. The isbnsearch system is a distributed, open-source isbn-lookup system for bibliographic data.
It accomplishes the same thing as Net::Amazon only using public domain data.
