Le Livre de Poche (literally "The Pocket Book") is the name of a collection of publications which first appeared on 9 February 1953 under the leadership of Henri Filipacchi and published by the Librairie générale française, a subsidiary of Hachette. In terms of its influence on the mainstream book market, it shares a similar popularity in France as publishers like Penguin and Signet do in English-speaking territories. Source: Wikipedia (en)
