Session 2: Love at the Library: Introduction to the Art of Letterlocking

The term “letterlocking” refers to the process by which letters, in this case on paper, were folded and secured in order to prevent the information contained within falling into unintended hands.

Conservator Jennifer Jarvis will briefly discuss the history of these documents before demonstrating how to make your own locked letters, which make perfect secret Valentines!
