Finally made it to the Beinecke Rare Book room in New Haven, at Yale. Amazing building and collection. It's a good thing there was glass between me and the Peter Pan books, I might have drooled on them 😃.
Somewhere in the stacks are books I've sold to the institution as well as an archive of Margaret Wise Brown papers and manuscripts that I originally brought to market. The archive changed hands multiple times, but I was happy to learn it eventually returned close to home.
