I stopped updating this guide in February 2003, after eight years online. I plan to leave it online for the foreseeable future and hope that enough links are still alive to make it useful.
I know that the guide contains many dead links and omits many valuable new sites. For a comprehensive, well-organized, and up-to-date guide to philosophy on the internet, I can recommend Tom Stone's EpistemeLinks.
