Some really cool (my opinion) video clips are on the Anthology Film Archive website. The AFA has one of the world’s most extensive collections of avant-garde movies, including an impressive amount of paper materials documenting the history and practice of American and international independent film and video. It also holds a remarkable collection of audio recordings which constitutes an invaluable oral history of avant-garde/independent movies.
Especially relevant to Greenwich Village history is the film clip titled “New York Downtown” which is a 9 minute silent clip that includes Astor Place, Grace Church and Washington Square Park. It’s undated, but from the cars and style of dress, as well as the cobblestone streets, I’d guess it’s either from the late 1940s or 1950s.
There’s also one titled “W 8th Street Heading West”, this time in color but also undated. Again, from the style of clothes and cars I’d guess it’s from the 1960s or 1970s.
