The code4lib Conference was born in a chatroom discussion in November 2005*. code4lib members quickly coalesced around the idea, and Jeremy Frumkin stepped forward to host it at Oregon State University. It was such a success that attendees immediately set about organizing the next one, which was held at the University of Georgia in Athens, GA, hosted by the Georgia Public Library Service. In 2008 we were back in Oregon, this time Portland, again made possible by Mr. Frumkin and the rest of the crew at OSU.
