@cadwellsocialcoop Have you looked at Bluestockings, the volunteer-run Manhattan NYC bookstore? http://bluestockings.com/about/our-structure/ Be sure to look around the site too at other radical organizations they partner with/know about/recommend to others in NYC and elsewhere. Don't have the time/spoons to do more research but that should be a place to start!
The Wandering Shop is a Mastodon instance initially geared for the science fiction and fantasy community but open to anyone. We want our 'local' timeline to have the feel of a coffee shop at a good convention: tables full of friendly conversation on a wide variety of topics. We welcome everyone who wants to participate, so long as you're willing to abide by our code of conduct.
