Personally, even though a library isn’t necessarily a means of production, I don’t think it would be not be welcomed under a communism environment. I feel the concept of a library and how they work overall is similar to what communist might be looking for in general from such a service.

Like I said depending on the environment, you can make small changes to how libraries work to fit it under communism. It doesn’t *have to be like that just because it is in certain locations with their own ways of doing things.

I understand communism to be a classless society, to have Collective (or common) ownership of the means of productions. Along with the absence of money eventually. Or at least it aims to for most of these things.

Libraries meet most of this, if not all of it.

Libraries could easily be adapted to fit Communism, most of the ground work is already set up, you might have to make some changes for it to work under communism as defined.

While they might not be communism they do share a lot of similar principles to communism. While their might not be a lot of specific production, collective ownership is also an important key to communism, which libraries share.

One person can borrow a copy of a book and then months later another person could get that same copy in their own household.
