The horse picks his way carefully up the stony creek bed, breathinghard as the climb grows steeper. There are hardly any roads here in Lee County, deep in the mountains of eastern Kentucky. So if you want to reach the tiny communities scattered among the hollows, this creek bed is about the only way to get there. On this particular day in 1936, a young woman named Grace Overbee is making the trek. And loaded into two heavy saddle-bags behind her is the reason for her trip-50 pounds of books and magazines. This horse, this woman, and these books together constitute the local branch of the WPA’s Pack Horse Library.2
