OS maps online
The National Library of Scotland has completed its project to put the complete 25-inch-to-the-mile Ordnance Survey maps for England and Wales online; these are the most detailed topographic maps from the 1840s to the 1950s. The maps are useful for local history, allowing almost every feature in the landscape to be shown. They provide good detail of all buildings, streets, railways, industrial premises, parkland, farms, woodland and rivers.
