The Johns Hopkins University Sheridan Libraries invite you to celebrate its newest major exhibition, Maryland, from the Willard Hackerman Map Collection, featuring exquisitely drawn maps and prints of the Chesapeake Bay and Baltimore from the 17th to the 19th centuries, and related rare books and ephemera from the John Work Garrett and George Peabody Libraries. The map collection was a gift to the Libraries by the late Baltimore developer, philanthropist, and Hopkins alumnus Willard Hackerman and his wife, Lillian, in 2016.

Experience the exhibition with co-curators Jim Gillispie and Paul Espinosa at a catered reception, followed by a 5 p.m. talk by renowned map collector, philanthropist, and tech guru David Rumsey in the "cathedral of books." One of the most important figures in cartography today, Rumsey is known for amassing "the dopest map collection on Earth" (Wired) and making it publicly available online.

4 p.m. reception; 5 p.m. talk. Free; advance reservations requested online or by email.
