Bazin started to write about film in 1943 and was a co-founder of the renowned film magazine Cahiers du cinéma in 1951, along with Jacques Doniol-Valcroze and Joseph-Marie Lo Duca. Bazin was a major force in post-World War II film studies and criticism. He edited Cahiers until his death, and a four-volume collection of his writings was published posthumously, covering the years 1958 to 1962 and titled Qu'est-ce que le cinéma? (What is Cinema?). A selection from this collection was translated into English and published in two volumes in the late 1960s and early 1970s. They became mainstays of film courses in the English-speaking world, but were never updated or revised. In 2009, the Canadian publisher Caboose, taking advantage of more favourable Canadian copyright laws, compiled fresh translations of some of the key essays from the collection in a single-volume edition. With annotations by translator Timothy Barnard, this became the only corrected and annotated edition of these writings in any language.
