See maps from this series

The New Series of the Geological Survey of England and Wales (GSEW) was officially inaugurated in 1900 with a standard sheet size and numbering from north to south and left to right. The basemaps were the second edition of the Ordnance Survey (OS) maps introduced in 1885. GSEW maps 1-73 actually followed the New Series Layout from 1885 and have the New Series sheet number in brackets beside the Old Series numbers.
