Specialized libraries on Libby

Hi all, I know we're all always on the lookout for free libraries that are open to all. I wanted to share two I came across on Libby-- Organization for Autism Research (OAR) and Queer Liberation Library (QLL). Both are free and anyone can sign up.

I would also love to know if anyone else has come across free libraries on Libby that specialize on certain topics or serve a particular group.
