At present there are a reported 850 films available. The list includes work from ITVS, PBS, National Geographic, and several notable independents including Icarus Films and Kartemquin Films. Titles that might be familiar include: The American Ruling Class, Biggie and Tupac, Cosmos, Father Roy: Inside the School of Assassins, The Life and Times of Allen Ginsberg, The Times of Harvey Milk, Trembling Before G-D, and T-shirt Travels.
Even the lesser known titles such as Agile Mobile Hostile, a film about R & B legend Andre Williams, and loudQUIETloud: A Film About the Pixies look cool.
If you know anyone planning to teach a distance ed class, this site should be given the once-over cause there's a lot here that have been used in courses at AU and could really enrich an online course.
