Handspeak
by Jolanta Lapiak · Handspeak
Reference site built by a Deaf native signer: a video dictionary of thousands of signs plus written tutorials on ASL grammar, classifiers, non-manual markers, fingerspelling and Deaf culture, so lookups sit inside linguistic explanation. The one dictionary worth keeping: unlike Signing Savvy or app dictionaries it wraps lookup in grammar and culture articles, and the core site is free (an optional patron tier only removes ads).

Signing Naturally: Units 1-6 Student Set
The curriculum most US college ASL programs teach from, by Deaf authors Ella Mae Lentz, Cheri Smith and Ken Mikos.

ASL University (Lifeprint)
Deaf professor Bill Vicars posts his entire university ASL curriculum free: dozens of lesson pages across four levels, each pairing vocabulary video with grammar explanation, fingerspelling drills, practice sentences, quizzes and Deaf culture notes. Teaches grammar and culture rather than isolated signs, and is completely free — the paid instructor-tracked version adds only documentation, so the free path loses nothing.
