[Air-l] Information/research request

Dear colleagues, I'm looking for citations (with urls if available) of any/all meta evaluations done on community networks and community technology centers in the U.S. I'm aware of CTCnet's site and publications, NTIA's, etc. etc., but just curious if any of you have been able to find a source where these have been researched and cited in academic literature in total? Also, I am eager to know about the nuanced differences between CTCs and CNs - is there a working definition? Thank you! RG Lentz UT Austin
