That’s a pretty room, but it doesn’t seem ideal for a library. If you’re trying to study / concentrate it would be loud: too many people, a big open space with hard surfaces, etc.

If you were waiting to meet up with a friend at the library, that’s a great room for that – as long as when that friend arrives you’re allowed to talk to them at a normal volume. But, you don’t need a room that huge for just meeting up at the library.

If you were allowed to just hang out and chat at normal volume, that would be nice. Especially in places with awful, cold winters, a big, open space like that would be so nice when you’re always stuck inside. But, with all those hard surfaces people would get louder and louder to make themselves overheard over all the other noise.

If the library hosted events of various kinds, that would be an amazing event space. Science fair type things, science demonstrations, a reading by an author followed by a Q&A, a charity ball, etc. It just seems not ideal for quiet reading, studying, etc.
