• SIGIA-L: Established by the ASIS&T Special Interest Group on Information Architecture in April 2000, SIGIA-L has emerged as the most popular discussion list dedicated to IA, sporting over 1600 subscribers. Traffic averages about 10 messages per day; available in digest form. The best archive of SIGIA-L was created by Andrew McNaughton in March 2001. More information.
• CHI-WEB: Many IAs participate in this discussion list, sponsored by the ACM's Computer-Human Interaction SIG. More information.
• InformationDesign.org: Offers two lists which address the closely related topic of information design: InfoDesign List (low-traffic, moderated) and InfoDesign-Cafe (unmoderated). Archives of both lists are available. More information.
• Lista de Terremoto.net: Spanish language discussion of information architecture and usability. Begun in January of 2001, Terremoto now has over 110 members. More information.
