Is there a sign language that can I find for Russian ? I am interested in how it compare with American Sign Language.
Of course Russian has a sign language. You can look for "Русский жестовый язык" and "Сурдоперевод" in the internet.
Start, say, from this Wikipedia article
Russian has its own sign language, and I can share a textbook of it, in Russian, Гейльман И.Ф., «Знакомьтесь: ручная речь», Москва, «Загрей», 2001, 2 MB.
