How many volumes does the novel "Remembrance of Things Past" consist of?

"In Search of Lost Time" —also translated as "Remembrance of Things Past" — is a novel in seven volumes, written by Marcel Proust (1871–1922). It is considered to be his most prominent work, known both for its length and its theme of involuntary memory. It gained fame in English in translations by C. K. Scott Moncrieff and Terence Kilmartin as "Remembrance of Things Past", but the title "In Search of Lost Time", a literal rendering of the French, has gained usage since D. J. Enright adopted it for his revised translation published in 1992.

"In Search of Lost Time" follows the narrator's recollections of childhood and experiences into adulthood during late 19th century to early 20th century aristocratic France, while reflecting on the loss of time and lack of meaning to the world. The novel began to take shape in 1909. Proust continued to work on it until his final illness in the autumn of 1922 forced him to break off. Proust established the structure early on, but even after volumes were initially finished he kept adding new material and edited one volume after another for publication. The last three of the seven volumes contain oversights and fragmentary or unpolished passages, as they existed only in draft form at the death of the author; the publication of these parts was overseen by his brother Robert.
