Copperplate

Northern Home Counties. Charles Knight was a significant London publisher, best known for his association with The Society for the Diffusion of Useful Knowledge (SDUK), for whom he published a number of educational works, including maps. Amongst these was an atlas, originally published in c1830 by Baldwin & Cradock on behalf of the Society. From 1834 publication passed to Charles Knight, who secured the rights to the maps after the demise of the SDUK in 1846. Knight re-issued them in his Imperial Cyclopaedia, adding to the original sectional UK maps a number of new ones of individual counties. The date of 1852 is often ascribed to the Cyclopaedia, but as this appears only a preface it may be that the maps appeared earlier in partworks, with collected prelims being issued for binding with them once the series was completed. Reproduction was by lithography, and maps were finished with outline hand colour to mark county and/or divisional boundaries, as here.Uncommon.
