On December 20, 1938, the Johnson County Pack Horse Library was established, which is often considered the precursor to the modern Johnson County Public Library. The program was headquartered in a room in the historic Mayo Mansion and was operated by May Stafford. Stafford, along with many other women, circulated books throughout the county on horseback until the establishment of the Johnson County Public Library on February 3, 1947. It was housed in the former Paintsville Public Library Building until the 1960s when the library moved into its current location on Main Street in Paintsville.

The Patricia Patton Kentucky Room contains numerous items on local history including census records, photographs, and legal documents. There is also a microfilm collection of both The Paintsville Herald and The Big Sandy News.
