Megan pointed me to the ADay of Archaeology project. This project was conceived of during one of our Day of Digital Humanities projects and builds on the idea. It serves partly as community outreach for archaeology:
The Day of Archaeology 2011 aims to give a window into the daily lives of archaeologists. Written by over 400 contributors, it chronicles what they did on one day, July 29th 2011, from those in the field through to specialists working in laboratories and behind computers. This date coincides with the Festival of British Archaeology, which runs from 16th – 31st July 2011.
I also note that they had far more participants in their first year than we had even in our third! We need to learn from them.
