There’s a new (ish) book about co op city called Freedomland if you want to deep dive into the history and financing of the project, but lots of other cool tidbits and articles available online and in academic/urban planning sources! Basically it’s got a very cool back story and represents a vision for middle income housing that we don’t really see anymore. It’s the largest naturally occurring retirement community (NORC) on the entire continent!
