Hi Pat
The Ludlow webpage is in the process of being transferred and will reappear shortly somewhere in the University of Denver Dept of Anthropology's webpage. There is one page that was set up as part of a teacher's institute at <http://coloradodigital.coalliance.org/cfindex.html>. Also on-line is an article by Phil Duke and Dean Saitta in Asemblage "An Emancipatory Archaeology for the Working Class" <http://www.shef.ac.uk/assem/4/4duk_sai.html>.
