The US Access Board is a federal agency charged with developing guidelines and standards about accessibility that will allow people with disabilities access to the built environment, public transportation, information technology, and medical diagnostic equipment. They deal both with the ADA (Americans with Disabilities Act) and the ABA (Architectural Barriers Act).
Last year, they set up a YouTube channel as part of their information dissemination strategy. You can find it here: https://www.youtube.com/channel/UC5tRWTtV5eSw68N3tSpmyWw
