Linguist List. The most comprehensive link you'll ever need for serious linguisticizing. (IPA font and other fonts here.)

Classics Resources . Here you'll find Sanskrit dictionaries, Latin and Greek grammars, and everything else you could imagine. Highly recommended--and it saves me a lot of space.

Oxford English Dictionary. The venerable institution in electronic form. You must be on a UMass server to access this (it checks to see where you're calling from).

American Dialect Society . Just what it sounds like.

IPA Font for the Mac. Windows users are on their own.

Silva Rhetorica. Useful resources for the study of rhetoric.

Language Variety. Overview of what is meant by "language variety."
