While updating my References page, http://maxqnz.com/References.html, I found that my Indo-European dictionaries link was dead. Scouting around for it, I found a nice-looking replacement, with an extremely unwieldy URL which I won't post here. I also found this cool graphic http://www.bartleby.com/61/indoeuro.html, that seemed very apt, almost Zoroastrian somehow. I'm not sure if Karen Chung's site has been mentioned here before, but she has some very good links on her page as well.
