The alphabetically arranged articles often criticize the Roman Catholic Church and other institutions. The first edition, released in June 1764, went by the name of ''Dictionnaire philosophique portatif''. It was 344 pages and consisted of 73 articles. Later versions were expanded into two volumes consisting of 120 articles.
