Salvete omnes,
Here are a few links to reliable websites in English about the Etruscans, received at a lecture about the Etruscan language wednesday :
http://www.ou.edu/class/ahi4163/files/main.html : About Etruscan art and language
http://www.mysteriousetruscans.com : Excellent information about all Etruscan-related subjects
http://www.nyu.edu/fas/center/ancientstudies : By clicking on "Institute for Etruscan and Italic Studies", you can read the periodical "Etruscan News" (recent finds, excavations, articles...)
http://www.bdp.it/parco/percorsi/percorso9/suoni/etruscan/ido_aulesin.mp3 : Hear a fragment in Etruscan !
Valete,
