The museum exhibits mounted birds and animals, an herbarium of Delaware County plants and other areas, such as fossils, shells, and corals from around the world; animal skulls, bird nests and eggs, butterflies, insects, and miscellaneous other collections such as maps as old as 1810, Native American tools and pottery, glass bottles, late 1800’s radios and radio vacuum tubes and microscopes.

The displays and research collections of minerals include many from famous localities in the area. The museum also houses the original plate blocks used to print Samuel Gordon’s 1922 Mineralogy of Pennsylvania. Additionally, specimens brought from the mineral prospects of the West by members of the Delaware County Institute of Science during the 1800′s can be viewed and studied.
