The library can be found in Sewickley, Pennsylvania, a borough that is located 12 miles (19 km) west northwest of Pittsburgh along the Ohio River.

Partial funding is provided by the Allegheny Regional Asset District and the Commonwealth of Pennsylvania According to Mr. Bayard H. Christy in a report prepared for the Home and School Association of Sewickley on November 8, 1912, the Sewickley Public Library owes its origins to the arrival of a whiskey boat at the Saw Mill landing one Saturday evening in the winter of 1872-73.

"The consequent riot and disorder...led some, interested in the welfare of the young men, to think that such things would not be, had we a place for proper and rational amusement and self-improvement."

Clause, he stated, "In presenting this library, it is my desire that it should be the property of the entire valley, yet under the existing conditions, there is no way this can be done, as there is no way the matter can be handled except to deed it to the School District of the borough of Sewickley.

In the ensuing years, Osborne and Edgeworth School Districts also supported the library until 1956 at which time a jointure of eleven municipalities comprising Aleppo, Bell Acres, Edgeworth, Glenfield, Haysville, Leet, Leetsdale, Osborne, Sewickley, Sewickley Heights and Sewickley Hills, formed the Quaker Valley School District.
