[DupySite] DupyBook Update

Right now I'm working on an update to the DupyBook web application that I wrote for Kristen. Currently, there's no way to edit an entry once its been created. Of course, this would be a really useful feature, especially for fixing entry mistakes or moving a book from the wish list to the book list. I think I'll accomplish this by make the book titles link to an Edit page which receives the book's id via an argument in the URL. Shouldn't be too hard, but will require some time and some fighting with my lack of PHP skills.
