Highlights from the Bartholomew Archive
Half-inch to the mile maps
See Scotland half-inch list
Colourful and easy to use, half-inch to the mile (1:126,720) maps became Bartholomew's trademark series. Associated mainly with recreation, these maps were popular and influential. The series sold well, particularly with cyclists and tourists
Reduced Ordnance Maps
Bartholomew based their half-inch maps on more detailed Ordnance Survey mapping at one-inch to the mile (1:63,360). The firm had published 'Reduced Ordnance Maps' of Scotland, England and Wales at this scale from the 1890s. These maps were progressively revised and updated with new information.
Layer colouring introduced
See England and Wales half-inch list
The maps were distinctive for using different layers of colour to represent landscape relief. A subtle and innovative gradation of colour bands were employed for land at different heights. Lighter greens were used for low ground closest to sea-level, darker greens and browns for higher ground, with white used for mountain tops. This was both innovative and influential.
John Bartholomew junior (1831-1893) first used the firm's trademark layer colouring in Baddeley’s Lake District Guide (1880). His son, John George Bartholomew (1860-1920), later went on to refine the style.
Colour layering is a feature of the half-inch maps used in two interactive Bartholomew resources:
Survey Atlas of Scotland
Survey Atlas of England and Wales
Half-inch maps feature as regional topographic maps in Bartholomew’s 'Survey Atlas of England and Wales' (1903). The firm continued to publish this series at the half-inch scale until the 1970s.
