W, or the Memory of Childhood (French: W ou le souvenir d'enfance), is a semi-autobiographical work of fiction by Georges Perec, published in 1975. Perec's novel consists of alternating chapters of autobiography and of a fictional story, divided into two parts. The autobiographical thread is a collection of uncertain memories, as well as descriptions of photos which preserve moments from Perec's childhood. The memories in the first part of the book lead up to Perec's separation from his mother when he was evacuated in the Second World War. The second part recollects his life as an evacuee. The adult narrator sometimes provides interpretations of the childhood memories, and often comments on details of the memories which his research showed to be false or borrowed.
