OS 311865-1947Ordnance Survey: Boundaries Branch: Boundary Record Maps (New Sketch Maps)
This series consists of boundary record maps - manuscript maps produced by the Ordnance Survey to record public boundaries after the discontinuation of boundary remark books in 1893. The purpose of these maps was to show the mereings of a boundary for verification (a mere is a landmark or object indicating a boundary). They are thus the successors to the boundary remark books and the boundary sketch maps. They are manuscript documents because no published mapping, other than at one inch to a mile, was available. Boundary record maps were superseded in the mid 1930s by six-inch and 1:2,500 revised boundary maps.
They relate to English, Welsh and Scottish boundaries.
