The initial order of the books is arbitrary but you can sort them in different orders. Clicking on a title will expand or collapse that book's information. The information first shows publishing facts about the book. Following that is my view of how much Perl you need to grok the book, my rating from 1-10 and my category designation for the book. I haven't reviewed it.
Unrated books sort at bottom when sorting by rating.
Then for each book there is a blurb, two menus and a link. Clicking on the link will get the current prices of the book from a selected set of web booksellers. On the prices page you can go directly to the book page on the bookseller's site. Soon I will create associate accounts so you can reward me for this project with kickbacks if you so desire. Currently there are only 20 books listed but my goal is to cover every book which has Perlish content.
