Bookstore Page

As suggested in this thread, a nice additional feature would be a "Bookstore" page that collects the books from the different nodes. Perhaps that page could be ordered by the site taxonomy. (So all the books from "crafts" pages would be in one group, all the books from "web design" pages would be in another group, etc.)

You could close the loop by having links back to the different articles from the bookstore page. This would allow people who are browsing the books see links to related articles.
