These maps are invaluable for historians and genealogists. More than 2,100 titles have been issued in this major series of reprints of Old Ordnance Survey Maps of towns throughout Britain and Ireland. Most of the maps are highly detailed, taken from the 1/2500 plans and reprinted at about 14 inches to the mile. They cover towns in great detail, showing individual houses, railway tracks, factories, churches, mills, canals, tramways and even minutiae such as dockside cranes, fountains, signal posts, pathways, sheds, wells, etc.. Each map includes historical notes on the area concerned.
