8. The colossal project to redesign and rewrite Diderot’s Encyclopédie, now under the direction of Parisian publisher Charles-Joseph Panckoucke, was announced in December, 1781, with a prospectus for subscribers. The Encyclopédie méthodique (conceived at this point as 26 dictionaries and seven volumes of plates) would contain a systematic and fully cross-referenced compendium of knowledge arranged by subject rather than alphabetically. Each finely printed volume would be written by a leading expert in the field. Both the quarto edition (42 vols.) and the octavo (84 vols.) were offered to the public at the same subscription price of 672 l.t. The subscription would close on July 1, 1782, after which the price would be 798 l.t. The entire series was to be completed in five years.
The failure of this prospectus to attract subscribers induced Panckoucke in March, 1782, to abandon the octavo edition, shorten the subscription period, change the financial terms, and issue a new prospectus. This time he generated a frenzy of interest, and the project was able to move forward. The tortured history of the Méthodique is detailed in Robert Darnton, The Business of Enlightenment (Cambridge, Mass., and London, 1979), pp. 395–519.
