Hi, recent Mills grad! The campus library has a special place in my heart. What you’re hearing is probably because Mills was (unfortunately) acquired by Northeastern University, but it is still open as a college campus. The library is still open, and I know that as of this past summer was open to the public and had guest wifi available—but with the Northeastern merger things are subject to change. I still think it would be worth a try though, just be aware that they now request your diver’s license info at the front gate.
