New essay published today! I found a weird little illustrated book in the Posner Collection at Carnegie-Mellon University and chased down its origins because it seemed like a fun thing to do. It was! Cameo appearance by @overholt@glammr.us, who was very helpful, as librarians tend to be. #books #literature https://pghrev.com/les-heures-de-marguerite-de-beaujeu-an-archival-adventure/
