The Grayson County Public Library was first located in what was formerly the St. Joseph Elementary School on North Main Street, Leitchfield. It occupied the two classrooms on the main floor, the connecting hallway, the office over the stairs, as well as all the entrances and exits on the main floor. In August of 1976 the Grayson County Public Library Board signed a lease with the St. Joseph Catholic Church of Leitchfield, KY for the use of this space. The Library stayed in this location for four years.

Susan Ferguson(1987) and Bianca Gerbrandt (1988-1994) also served as Library Directors. Karen Gillespie retained her position as Library Director from 1994-2006. Lisa Jones began her position as Library Director in 2007 and retained this position until her passing in June of 2020.
