Sometime you may find yourself wondering one of the world's eternal questions: How many cutlers were in Sheffield during the 1850s? Well, you might not be actively seeking the answer to that particular query, but this incredibly extensive digital library created by the University of Leicester may help you solve other related historical questions. This digital library contains a host of local and trade directories for England and Wales from 1750 to 1919, many of which were previously only accessible by making a special trip to any number of local historical societies or archives. Curious visitors can search the directories through an interactive map of England and Wales in order to find the information that is most relevant to their interests. Currently, the project provides at least one directory for each segment from the interactive map from the 1850s, 1890s, and 1910s. Visitors can also search the entire digitized archive by keyword, location, and name.
