Main search process

Choose the map category that you would like to search from the left-hand list. These are grouped into National Grid and County Series, and then from most detailed to less detailed maps. Using the map controls or gazetteer, zoom in and click on your the area of interest to see which maps were published.

The sheets that you have selected are highlighted in royal blue, and brief records of them appear in the right-hand panel. For all Scottish maps, and all County Series maps, this includes specific dates, and you can also select these to view further information about a specific map sheet.

Gazetteer, National Grid Reference, and Counties/Parishes for searching

The Gazetteer at the top of the map allows you to locate your area on the map using modern place names from Nominatim, as well as by British National Grid Reference - - 2, 4, 6, 8, or 10 figures (ie. 'SE12', 'NT1234', 'TQ123456', 'SD12345678', 'SD1234567890'). You can also search using numeric Grid References as Eastings and Northings (ie. '123456,123456'). Further down, drop-down boxes allow counties and parishes (based on their names and boundaries in the 1940s) to be searched. In all cases, the map will then position to the place, National Grid Reference, county or parish that has been selected.

Background map

By default, the background map shows a modern Bing road layer. Select the drop-down list to choose Bing satellite or hybrid layers, ESRI ArcGIS streets or satellite layers, 1920s mapping from the NLS Historic Maps API, OpenStreetMap, or Ordnance Survey Opendata as background maps.
