The Asilomar Institute for Information Architecture (AIfIA) is a non-profit volunteer organization dedicated to advancing and promoting information architecture. My favourite quote:

“The emergence of Information Architecture (IA) as a formal discipline has gathered key areas of expertise together to provide a framework for the rational design of content-rich sites. IA provides the glue that allows content and services to work in tandem to satisfy user requirements, and the structure necessary to evaluate success in meeting those needs. Without IA, both users and creators of information-intensive applications are likely to suffer from wasted resources, time and effort; even worse, they won’t know where to start to make things better the next time.”
