The  Erie Public Library was established in 1897, the first in Pennsylvania  to be organized under the Free Library Act of 1895 providing that public  libraries could be established under school district auspices. The  formal dedication of the building at 27 South Park Row took place on  February 16, 1899. The building’s original tenants were the Erie School  District’s administrative offices, the Public Museum of Natural History  and the Public Library and the Art Club of Erie. Until 1969 the Erie  School District offices occupied the second floor while the library was  located on the first and basement levels.
In  1963 the State Librarian designated the Erie Public Library as the  District Library Center of Erie and Crawford Counties. The primary  responsibilities of the District Library Center was to provide free  inter-library loans, reference services and consultant’s services to the  branch libraries as well as to all the local independent libraries in  the two county area.
On  November 14, 1973, the Erie Public Library broke its direct ties with  the Erie School District and became the Erie Metropolitan Library, a  non-profit corporation with an independent Board of Directors.
The  Erie County Commissioners established a separate library, the Erie  County Public Library in 1949. The main purpose of the Erie County  Public Library was to serve the elementary schools of Erie County, which  were without libraries of their own. This purpose dictated the  direction the county library took in its formative years: that of a  library on wheels and a philosophy of outreach. The County Library was  established in the Priestly Avenue School in Lawrence Park, and in 1966,  moved again to an industrial arts building at 4212 Iroquois Avenue, the  present location of the Iroquois Avenue Branch Library.
The  Erie City and County Library formally came into existence on July 1,  1976. This library was a result of the merger between the Erie  Metropolitan Library and the Erie County Public Library. A merger had  been discussed since the 1960s. In 1973 an independent library  consultant was commissioned to study the feasibility of a merger. The  result of this study was the Machinski Report and the recommendation  was to merge. Serious negotiations between the board of Directors of the  Erie Metropolitan Library and the Board of Trustees of the Erie county  Library resumed in the fall of 1975. A $200,000 federal grant and  agreement by the Erie County Commissioners to provide financial support  to the Erie Metropolitan Library supplied the final impetus for merger.  The federal grant was used to implement the merger and to establish two  new branch outlets.
In  October of 1979 the Erie City and County Library was taken over by Erie  County government. The County Administration spearheaded the takeover  and signed an agreement with the School District of the City of Erie.  The agreement reduced annual funding by the school district until  contributions ceased on July 1, 1982, the first time since 1899 that the  library did not receive appropriations from the Erie School District.
With  the change in financial support came other major changes. The name of  the library became the Erie County Library System. The library became a  department of County Government and an Advisory Board was appointed and  all the staff became county rather than school district employees in  1982.
In 1996, after nearly 100 years of service, the main library on South Park Row closed its doors for the last time.
