The Pack Horse Library Project was a Works Progress Administration (WPA) program that delivered books to remote regions in the Appalachian Mountains between 1935 and 1943. Women were very involved in the project which eventually had 30 different libraries serving 100,000 people. Pack horse librarians were known by many different names including "book women," "book ladies," and "packsaddle librarians."[1]: 290 The project helped employ around 200 people and reached around 100,000 residents in rural Kentucky.[2]
