The American Association of Teachers of Slavic and East European Languages is one of our major professional organizations. The site provides information about the field and an excellent list of language programs at http://www.aatseel.org/intensive_language. It also covers other Slavic and East European languages, instructions on computer fonts, links to bookstores, and a list of graduate schools! for Russian and Slavics.
Another reliable professional organization, which covers social studies as well as language, is AAASS, the American Association for the Advancement of Slavic Studies.
The American Council of Teachers of Russian is part of the American Councils for International Education and dedicated to the study of Russian and to exchange programs with Russia and the former Soviet States. This is an excellent resource for programs, funding and even job listings.
Language Dictionaries online
For a more narrow list, you can limit yourself to the specifically Russian and Slavic dictionaries at http://www.yourdictionary.com/languages/slavic.html. Those include such delightful items as anatomical dictionaries and dictionaries of election terms.
But this Alphadictionary resource is a more general list with all kinds of languages from Abenaki to Zulu. Mostly human languages, but, yes, the list does include Klingon.
Language Mentor Links
The "Russian language mentor" site is unfortunately anonymous. However, it does have an excellent list of links which includes megasites, dictionaries, language resources and social studies resources. This replaces our former link to Robert Beard's materials at Bucknell University -- those materials are no longer available in their original form.
