British Encyclopaedia, or Dictionary of Arts and Sciences

The British Encyclopedia, or Dictionary of Arts and Sciences, claimed by its publishers to be a work "Comprising an accurate and popular view of the present improved state of human knowledge", was published at London in 1809 in six octavo volumes and around 150 plates.

The title page credits William Nicholson as the author, and much of the work was overseen by Jeremiah Joyce.

The work was published by a syndicate of twenty-three booksellers whose names appear on the title page of each volume, headed by the firm of Longman, Hurst, Rees, & Orme.

Each purchased shares and in due time received a proportional profit from the eventual sales.

[1] If Issitt is correct, given that Gregory's Dictionary appeared in two folio volumes and Nicholson's Encyclopedia was presented in six octavo volumes, it would seem that Joyce must have copied nearly the whole of Gregory's Dictionary into Nicholson's Encyclopedia.
