Library of Michigan

Planned to get library cards, and take a quick look around the library. We weren't going to visit the museum (mostly because we had other museum plans, which ended up falling through), but it turned out admission was free for Archaeology Day. We ended up spending most of the visit going through the museum, and watching a lecture, and didn't really spend any time in the library at all (other than getting our library cards).
Definitely plan to come back at some point, to dig through the archives if nothing else.
