Encyclopédie (18th-century French encyclopedia)

The Encyclopédie, ou dictionnaire raisonné des sciences, des arts et des métiers (French for 'Encyclopedia, or a Systematic Dictionary of the Sciences, Arts and Crafts'), better known as the Encyclopédie (French: [ɑ̃siklɔpedi]), was a general encyclopedia published in France between 1751 and 1772, with later supplements, revised editions, an index, and translations. It had many contributors, known among contemporaries as the Encyclopédistes. It was edited by Denis Diderot and, until 1759, co-edited by Jean le Rond d'Alembert.

The Encyclopédie is most famous for representing the thought of the Enlightenment. According to Diderot in the article "Encyclopédie", the Encyclopédie's aim was "to change the way people think" and to allow people to inform themselves. Diderot hoped the Encyclopédie would disseminate a vast amount of knowledge to the present and future generations. Thus, it is an example of democratization of knowledge, though the high price of the first edition especially (980 livres) prevented it from being bought by much of the middle class.

The Encyclopédie was also the first encyclopedia to include contributions from many named contributors, and it was the first general encyclopedia to describe the mechanical arts in much detail. In the first edition, seventeen folio volumes of text were accompanied by eleven volumes of engravings. Later editions were published in smaller formats and with fewer engravings in order to reach a wider audience within Europe.
