Research Library

Delaware County Historical Society (DCHS) encourages residents to visit the Research Library in-person to conduct research. Our Collection Services Manager will guide visitors through the process of how to search the collection and provide researchers with all of the resources available.  A list of DCHS resources are below.
DCHS’s Research Library is open during listed business hours. The research visit fee is $15 and provides you access to our entire collection and up to 10 pages of printed copies. An additional charge of $.50 per page will apply if more than 10 copies are needed. Join as a Friend/Member of DCHS for $30, (see memberships), and will have unlimited access to the collection throughout the year!
Any questions or inquiries should contact the Research Library at or 610-359-0832
