The Merriam-Webster Online Dictionary – The collegiate dictionary, good also for comparison with the OED.

ADS-L Archives Search Engine – A means of searching the ADS e-list archives from 1992 to the present. You can search for discussions of specific words and phrases (like “Big Apple”) or grammatical issues (like prescriptive grammar or Ebonics, for which see below). When it’s working properly, this is the most efficient way to search the archives. Thanks to Grant Barrett for creating and maintaining it.
The Dictionary of American Regional English – This is not an online version of DARE, but it is a good introduction to its methodology, including maps, examples, and quizzes for you to test what you know about American regionalisms.

Saussure & Chomsky
The two most influential linguists of the 20th Century have been Ferdinand Saussure, who established the principles of a non-historical scientific approach to language called Structuralism, which eventually led to Semiotics, and Noam Chomsky, who conceived of Transformational Grammar, a view of grammar as a “generative” process instead of a set of external handbook rules. These links are brief biographies and introductions to their work.
Sign Language & Primate Studies
The development of linguistic approaches to sign language has changed traditional definitions and understanding of language, and controversial work with primates (e.g., the chimpanzees Washoe, Lucy, and Lana, the gorilla Koko, and the bonobo Kanzi) has challenged Chomskyan linguistics.
Sociolinguistics, Psycholinguistics, Neurolinguistics
Linguistics has always been an interdisciplinary field, studying the social phenomenon of language but grounded in the natural science of phonetics. These three related disciplines under the broad linguistic umbrella have contributed some of the most important breakthroughs in our understanding of what language is, where it came from, and how it works. Psycho- and neurolinguistics have also called into question the Chomskyan linguistic model that has dominated the field for 30 years. Note that much of the material in these links is highly specialized and can be difficult. For an excellent and readable neurolinguistic approach to language, see Terrence Deacon’s The Symbolic Species: The Co-Evolution of Language and the Brain (in the Introductory Bibliography).
