The AHRC was for many years the first and foremost tool for art history research on the internet. It shares key resources and methods of online research so that art historians can find the resources relevant to their work.
I created it when I was an undergraduate in art history in 1995. It was updated for the last time in 2007. Today, Google is everyone's main research tool on the internet, but this specific resource is still a good place to learn what the internet has to offer art historians. My short essay "The Internet as a Research Medium for Art Historians", written then for novices, is still widely cited and its concepts remain relevant. The AHRC is also of interest as the earliest major effort to get fellow art historians interested in using the internet for research, and so it has a place in art history and in internet history.
