I've compiled alignment information from AD&D1, AD&D2, D&D3, Dragon magazines, and other game systems and placed it all on a website. Very detailed alignment descriptions are given along with references and a bibliography page. This information should be useful to players and DMs who want to stress the alignment aspects of roleplaying in their adventures. Also included is the good ole alignment test, a couple of articles on alignment tendencies and tracking, and a link to the most detailed "What D&D character am I?" quiz ever produced.
