What does "cum" mean in this sentence?

Answer

A cum B means like a B, also serving the purpose of B, a combination of roles.

dictionary : with; combined with; along with (usually used in combination):

"cum" is probably Latin. "with" from memory, but it's a long time since I studied Latin. Sorry.

Answer

"Along with". So  the room was a library but it was also used as a reading room and a bar.
