The Society for the Diffusion of Useful Knowledge, founded in 1826, was a Whiggish London organisation that published inexpensive texts 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 objects of publishing information to people who were unable to obtain formal teaching, or who preferred self-education. The Society was sometimes mentioned in contemporary sources as SDUK.
