There are more than 2,400 maps in this series of Old Ordnance Survey Map reprints, including groups in Berkshire & Oxfordshire. The maps are highly detailed. They are taken from the OS 1:2,500 (or 25 inch) maps and reduced to about 15 inches to the mile. Each covers an area of a mile and a half by a mile. They show streets with individual houses, tram tracks, railway tracks and even signals, factories, wharves and such details as fountains and water troughs. They will provide hours of fascination for historians and genealogists. The maps are neatly folded and each includes a specially written introduction to the area.

There re two versions of this map, showing how the area changed across the years. Note that the 1883 version is from the beautiful handcoloured 1st Edition and is fully colour printed.

Coverage stretches from The Circus southward to Bloomfield Avenue, and from Twerton Cemetery eastward to Archway Street, Dolemeads. The many features include East Twerton, Locksbrook, South Twerton, several cemeteries, Somerset Certified Industrial Home, Green Park station with railway approaches, Crescent Gardens, River Avon, Bath Spa station, Beechen Cliff, Abbey church, Henrietta Park, Queen Square. The Royal Crescent is split by the top margin. The city centre is shown in great detail with individual buildings neatly delineated. Each map includes various street directory entries, that for the 1883 map being from Kelly's 1902 directory and including The Circus, Gay Street, High Street, Milsom Street, New King Street, Queen Square and Southgate Street.
