For over 150 years, collecting, preserving, and sharing Delaware history has been at the core of the Delaware Historical Society’s mission. The Society’s collections now include about 3 million objects, books, manuscripts, and images that reflect life in Delaware from 1638 to the present. These are the essential primary sources that make it possible to tell the many stories that shape Delaware’s history.

Most of the items in the Society’s collection have been generously donated by the public. If you have something that might be suitable for the collection, please contact us. To learn more about the Society’s collections, visit Ask Caesar, the Society's online catalog.

In honor of the Society’s Sesquicentennial in 2014, we featured one of our treasures each month. You can view the items as often as you like online (below) to see just a few of our curators’ favorite things!

You can also visit us on YouTube for these and more Delaware Historical Society videos including workshops, instructional videos, brief glimpses into Delaware history and more!
