Proust and Signs (French: "Marcel Proust et les signes" ) is a 1964 book by Gilles Deleuze, in which the author explores the system of signs within the work of the celebrated French novelist Marcel Proust.
 It was translated into English by Richard Howard.
Valentin Louis Georges Eugène Marcel Proust ( ; ] ; 10 July 1871 – 18 November 1922), known as Marcel Proust, was a French novelist, critic, and essayist best known for his monumental novel "À la recherche du temps perdu" ("In Search of Lost Time"; earlier rendered as "Remembrance of Things Past"), published in seven parts between 1913 and 1927.
 He is considered by critics and writers to be one of the most influential authors of the 20th century.
The Marcel Proust Prize is a former literary award of France.
 Created by the municipal council of Cabourg, in Normandy, in 1972, it was awarded until 1994; the recipient was a work which evoked that of Marcel Proust.
 Writers were awarded 5,000 francs for their work.
James Grieve (born 1934) is an Australian translator of French literature and an author.
 His translations have included scientific works, books for children and two volumes of Marcel Proust's "À la recherche du temps perdu" (ANU, 1982 and Penguin, London, 2002).
 Grieve's translated second part of Proust's 7-part "Remembrance of Things Past" is the first completely new English translation since the 1920s.
 There were six other translators working on the other parts, for this project by Penguin.
 Grieve's Penguin translation received positive review from Alain de Botton who remarked: "... if one ends up with a favourite [of the 7 volumes] (mine was James Grieve, who did Volume 2)."
 Grieve is also the author of the language study text "Dictionary of Contemporary French Connectors" (Routledge, London, 1996).

Proust Was a Neuroscientist is a non-fiction book written by Jonah Lehrer, first published in 2007.
 In it, Lehrer argues that many 20th and 21st-century discoveries of neuroscience are actually re-discoveries of insights made earlier by various artists, including Gertrude Stein, Walt Whitman, Paul Cézanne, Igor Stravinsky, and, as alluded to in the title, Marcel Proust.
