For the creative community here, here is a good resource for avant garde films. Anthology Film Archives was founded in 1970 by Jonas Mekas, Jerome Hill, P. Adams Sitney, Peter Kubelka, and Stan Brakhage. Not necessarily names you would recognize right away, but they are very well known in the experimental film community here; an art school friend introduced me to this area in the 1980s.
AFA is working on making more of their collection available online and also provides links to other resources (See Film and Video on the Collections page).
