Greetings, this is my first post to this list, but I think it might be of interest to some. Sorry for any cross-postings.
I have developed a WordPress plugin that inserts book covers and book data from Open Library into posts and pages. It is an open source PHP product that is available for download from the WordPress server: http://wordpress.org/extend/plugins/openbook-book-data/. The PHP could be adapted to work outside WordPress. My support page is: http://johnmiedema.ca/openbook-wordpress-plugin/. The current version is 1.1.1 beta. It is the first release, and it is a beta release. Note it does require PHP 5.2 for the JSON library. This was not the default on my server; it was a simple switch on my control panel, but perhaps it is not so straightforward on your server, or you may not want to upgrade to avoid impacting older scripts. A check tests for the required JSON library function when the plugin is activated. It has only been tested in WordPress 2.5.1. A couple people have indicated a successful implementation. A couple others have had problems that appear related to their theme and other plugins. There has been quite a bit of activity at my site since I released it, and several downloads of the plugin, but I have received less feedback than I hoped. If you decide to give it a try, I would appreciate any feedback at the site, or at my email address: [EMAIL PROTECTED] I also plan to present on this product at the One Big Library Unconference. Maybe see you there. Thanks, John Miedema http://johnmiedema.ca
