Internet mailing lists are often hard to find, since there are so many. However, there's a Web page that supposedly lists all of them. It enables you to sort alphabetically or by category, and when you sort by category, you can get more detailed information on the list. The site appears to be a functional advertisement for a $99 tool (currently only Windows-based, but a Mac version is in the works and slated for November release - they'd better hurry) called InfoMagnet, which lets you find, search, and participate in LISTSERV-based mailing lists. From the sounds of it, Info-Magnet is a front-end interface to the often-complex LISTSERV commands.
In addition, another Web page enables you to search a database (maintained by Dartmouth College) of almost 6,000 mailing lists. The database is updated weekly, and this site has become one of my favorite tools on the Web. [ACE]
