Use the RIT Libraries Catalog to find videos related to Deaf Theatre and performers.If you need to find a video offsite, this short video shows you how to request an offsite video (ie, building 99). It takes a day or two for the DVD to be delivered to the Library Services Desk, where you can pick it up.
Check out the Heart of Deaf Culture DVD, which is also available as a website. See links below. The Deaf Theatre website also has online videos.
