Quantum Gravity in the Americas III Proceedings
Room 201 Osmond

The conference was lively with a lot of discussions. Several participants (and others who could not come to the conference) suggested that proceedings be made available on the web. The Scientific Organization Committee concurred.

These proceedings were prepared by Mikhail Kagan and David Sloan. They contain slides of all but two talks and audio for most talks. (Unfortunately, because of a technical problem with recording, audio files of some talks are missing.)

They, as well as Florian Conrady, Jonathan Engle, Golam Hossain, Tomasz Pawlowski, Param Singh, Victor Taveras, Kevin Vandersloot took care of the AV arrangements during the conference. Hannah Williams provided the web support and Jeff Minelli provided the computer support at the conference and for these proceedings. Kathy Smith and, especially Randi Neshteruk, looked after all the administrative matters. To all these individuals, we are most grateful.
