Representatives from the local AARP group, which was disbanding, met with the East Pennsboro Township Commissioners to discuss options for volunteer opportunities for the AARP members. These two groups felt that a local library would be of great benefit for both the AARP volunteers and East Pennsboro Township residents. Bob Gill, George DeMartyn and several AARP volunteers approached the West Shore Library (now Fredricksen Library) with this proposal to create a branch of West Shore Library. Since funding for this project was limited, the township agreed to provide a rent-free space and utilities on the second floor of the Township Building. AARP volunteers agreed to staff the new library. East Pennsboro Branch Library opened its doors to the public on Monday, October 7, 1985. It is the only branch library in the Cumberland County Library System.

Sometime later, a book drive was sponsored by Jim Tezak and Boy Scout Troop #87 of Enola. Some of these books made their way onto the shelves, while others were sold to purchase new books. Hope Hetzel, the Director of the West Shore Library, made daily visits to bring additional books for the collection, to deliver special materials requested by residents, and to assure volunteers were available to staff the branch during posted hours.

In December 2016, East Pennsboro Branch Library relocated to the ground floor of the Township Building and is now conveniently located on the same floor as the Friends book store as well as the Schaner Adult Center.
