The purpose of the Parmly Billings Library collection is to convey the history of Billings and Yellowstone County (Montana) in photographs, images of noteworthy documents and monographs. These records include information about the pioneers who first settled in the area, first buildings and industries; as well as notable books, historic documents and letters. At the time the items were chosen for inclusion in the Montana Memory Project, they were part of the physical collection in the Montana Room at the Parmly Billings Library in Billings, Montana.
