This CD contains images of the Ordnance Survey second edition 25-inch maps of Derbyshire which were produced between 1896 and 1900. The scale is 1 to 2500 or 25.344 inches to the mile. These maps covered the whole of the built up and cultivated areas of Derbyshire. They show almost every detail of the landscape at its true scale, including roads, which on most maps are exaggerated to make them stand out. The maps do not show contours of the landscape but do show some spot heights. Enclosed areas of land show the acreage of the plot and a reference number. This number is a reference to an entry in a record book, which gave a detailed description of the plot and its use. Unfortunately, very few of these books have survived. These maps were used as a basis for valuation of property under the Finance Act (1909-10).

The maps, of which there are almost 750 in the Derbyshire series, were scanned from the maps held by the Derbyshire Record Office, Matlock, with their permission and kind help. A few of the missing maps were supplied by local Libraries and Record Offices. The maps are the equivalent of what is now A0 size measuring about 40ins by 30ins. They have been reproduced at 300dpi giving a very detailed image. Most of the maps are in good condition considering that they are over a hundred years old, but a few are showing the wear and tear of time and some electronic cleaning has taken place. Wherever possible, better copies were obtained when a map was in a poor condition.

There were three editions of these Maps. The first was published between 1872 and 1883, the second 1896 to 1900 and the third 1912 to 1921.
