NOTE, 5.9.2008: Five months into the project, and I'm only about 30% done with adding archived books. On top of that, I haven't bothered to fix obvious quirks like stripping slashes from database results and reworking my dumpy admin interface.
Despite all that, I'm already thinking about a major overhaul of the site. I'm investigating CakePHP, Eclipse, and other ways of improving quality control and adding pointless features. Stay tuned!
