In Britain, the Council for British Archaeology lists this summer’s
fieldwork sites on
http://britac3.britac.ac.uk:80/cba/briefing/field.html. Or
for more digs you could try Current Archaeology, Andrew Selkirk’s pages at
http://www.compulink.co.uk/~archaeology/digs.htm.

Archaeology is one of the few sciences that welcomes amateurs, but be warned,
dig organisers tend to work you very hard.
