To better serve our researchers, the Delaware Historical Society Research Library will be closed from Tuesday, January 3-Friday, March 3, 2017 for reorganization. While staff will be unable to accept online research requests during this period, researchers will still be able to access our online catalog, Ask Caesar. For your convenience, the library will remain open at the following times:
Mondays, 11:00 a.m.-7:00 p.m.
Saturday, January 21, 10:00 a.m.-4:00 p.m. and Saturday, February 18, 10:00 a.m.-4:00 p.m.
Thank you for your patience and continued interest in the Delaware Historical Society. Our library staff looks forward to serving you when we resume normal operating hours on Monday, March 6, 2017.
