The aim of the project was to improve access to local and trade directories for the period 1750-1919 by making a substantial collection of English and Welsh directories available online as a Digital Library of Historical Directories. This digital resource comprises in total some 600 directories, covering every English county together with Wales, and ranging widely over the period 1750-1919 (the latter cut-off point chosen for copyright reasons). There is a particular focus on the 1850s, 1890s and 1910s, with at least one directory provided for each county in each of these decades. The digitisation of the volumes involved a two-stage process, in which (1) the hard-copy source was scanned to produce a graphic image of each page, and then (2) those images were processed using OCR software to generate a machine-readable text file.An online version of this resource can be found on the Website of the University of Leicester. This data collection includes the following directories:- The Post Office London Directory for 1916. County Suburbs (1916)- The Post Office London Directory for 1917. County Suburbs (1917)- The Post Office London Directory for 1918. County Suburbs (1918)- The Post Office London Directory for 1919. County Suburbs (1919)
