In learning about ASL and Deaf culture, I've accumulated a variety of online resources. I've presented some of those resources here, and I hope you'll find them useful and interesting.

• Sign Language Dictionaries

• ASLWeb - A project of the Michigan State University Communications Technology Lab. Contains a dictionary of several thousand signs with QuickTime movies to demonstrate the signs. This is my favorite ASL dictionary site.
• HandSpeak - An interactive dictionary of ASL signs and Deaf culture
• Animated ASL Dictionary - Animated GIF diagrams of some signs.

• Deaf Culture

• National Association of the Deaf
• Deaf Resource Library
• Omer Zak's DEAF-L Web Site
• Gallaudet University

• Mailing Lists

• The DEAF-L mailing list is a well-established list, gatewayed to Usenet.
• Deaf mailing lists on Yahoo Groups

• Books

A full list of books relating to ASL, Deaf Culture and so forth can be found on my Reading List.

• Other Resources

• TTYs (teletypewriters) are used for communication by and with Deaf people. Some companies which make TTYs are Ameriphone, Ultratec and Krown Research.
• Gallaudet University distributes a TrueType font for Windows and Macintosh PCs which allows you to type using the fingerspelling alphabet. You can download it from here.
