The Society for the Diffusion of Useful Knowledge

The
Society for the Diffusion of Useful Knowledge was founded in 1826 and
was a London organisation that published inexpensive but high quality
maps intended to adapt scientific and similarly high-minded material for
the rapidly expanding reading public. It was established mainly at the
instigation of Lord Brougham with the ambition of publishing information
to people who were unable to obtain formal teaching, or who preferred
self-education.  Particularly the town plans that were produced often
included beautiful and intricate vignettes of the cityscape. 
Importantly, SDUK (as it is often called) recorded the latest
discoveries in Australia and America at the height of the European
exploration of both nations. It received quite a lot of criticism from
scholars and the elite due to its progressive influence in education
reform; however despite its opposition, the forward-looking ideals of
the Society for the Diffusion of Useful Knowledge played a meaningful
part in nineteenth-century educational history.
