Since LJ is still being a bit of a butt, I've spent a good chunk of the afternoon browsing through the Prelinger Archives . Founded in 1983 by Rick Prelinger in New York City. it has grown into a collection of over 48,000 "ephemeral" (advertising, educational, industrial, and amateur) films, from 1927 to 1987. The old fifties sex education films alone are worth the time it takes to download, and for a great laugh, get parts 1 and 2 of "Perversion For Profit", and anti-porn film put together in the mid-sixties by Charles Keating.
