DETAILED maps offering a fascinating glimpse into how Burton and South Derbyshire developed from Victorian times to the 1950s are now available free online.
Images show how places such as Burton, Tutbury and Swadlincote have changed across the years, ranging from 1884 to 1949.
The series of Ordnance Survey maps show how towns and cities across the UK have spread into the countryside and how the road and rail network developed.
Individual buildings and streets can be identified clearly and smaller features can be seen including post boxes, bollards on quaysides and mile posts.
Chris Fleet, Senior Map Curator at National Library of Scotland (NLS), said: “These new maps cover all of England and Wales and are immensely valuable for local and family history.
“People can search for the street their grandparents lived in or see how 19th century farmland has turned into today’s suburbs.”
The maps can be viewed over time for each place of interest.
They are available on the website of the NLS as a result of an extensive programme that has digitised historic maps across the UK.
The six-inch to a mile maps show all place names recorded by Ordnance Survey, including all street names in towns, and all smaller farms, hamlets and villages.
The website allows viewers to zoom on the maps to pick out the detail they are interested in.
The maps were surveyed for the whole country twice - first between 1842 to 1893 and then between 1891 to 1914.
They were subsequently updated regularly for urban or rapidly changing areas from 1914 to the 1940s. The result is that, for many towns, there are three to five editions of mapping between the 1840s and the 1950s.
They can be searched in a number of different ways, by place names, street names, post codes and grid references. They are also available via county lists.
