The series of directories produced by Kelly & Co were originally published in volumes covering several counties until the late 1920s, however many of these multi-county editions have been split and rebound as single county volumes by libraries and booksellers and it is now common to find early editions covering Staffordshire only although the 1850 volume was originally published as 'The Post Office Directory of Birmingham with Staffordshire and Worcestershire' and subsequent volumes were published as 'Kelly's Directory of Birmingham, Staffordshire, Warwickshire and Worcestershire'
Kelly's Directories covering Staffordshire were published in the following years:
1850 1854 1860 1864 1868 1872 1876 1880 1884 1888 1892 1896
1900 1904 1908 1912 1916 1921 1924 1928 1932 1936 1940
In addition to the volumes listed above which covered the whole county an earlier Kelly's Directory of Birmingham and Warwickshire published in 1845 also included the southern part of Staffordshire only.
