County road maps are available in most if not all courthouses. Older maps are published in county histories, county atlases, and in manuscript collections such as at the Historical Society of Pennsylvania, the state library, and the state archives. Useful city maps can sometimes be found in city directories. An interesting map showing the development of the commonwealth's counties is available for a nominal fee from the land records office (see Land Records). See also Henry F. Walling and O. W. Gray, 1872 Historical Topographical Atlas of the State of Pennsylvania (1872; reprint, Knightstown, Ind.: Bookmark, 1977), which has business directories and a place-name index.
Available at the state archives (with copies at the state library and the respective county recorder of deeds) are warrantee maps for twenty-four counties. Those for Fayette, Greene, and Washington were also published and indexed in volume 3 of The Horn Papers by W. F. Horn (New York, N.Y.: Hagstrom Co., 1945), but the preceding two volumes of text are mostly fiction (see William & Mary Quarterly, series three, 4 [1947]: 409–451).
