The museum exhibits mounted birds and animals, an herbarium of Delaware County plants and other areas; fossils, shells, and corals from around the world; animal skulls, bird nests and eggs, butterflies, spiders, insects, and miscellaneous other collections such as maps as old as 1810, tools, glass bottles, telegraph keys, 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.
The Library of the Institute houses several thousand books and other publications on the Natural Sciences. Many of these are period classics by authors who have been subsequently recognized widely for their scientific contributions. The Library includes numerous volumes of local significance and highlights a large 19th century series relating to Pennsylvania. The Library is a non-circulating reference collection that is accessible to the public upon request during operating hours.
