The group defines the term littérature potentielle as (rough translation): "the seeking of new structures and patterns which may be used by writers in any way they enjoy".
Constraints are used as a means of triggering ideas and inspiration, most notably Perec's "story-making machine", which he used in the construction of Life A User's Manual. As well as established techniques, such as lipograms (Perec's novel A Void) and palindromes, the group devises new methods, often based on mathematical problems, such as the knight's tour of the chess-board and permutations.
Oulipo was founded on November 24, 1960, as a subcommittee of the Collège de ‘Pataphysique and titled Séminaire de littérature expérimentale. At their second meeting, the group changed its name to Ouvroir de littérature potentielle, or Oulipo, at Albert-Marie Schmidt's suggestion. The idea had arisen two months earlier, when a small group met in September at Cerisy-la-Salle for a colloquium on Queneau's work. During this seminar, Queneau and François Le Lionnais conceived the society.
During the subsequent decade, Oulipo (as it was commonly known) was only rarely visible as a group. As a subcommittee, they reported their work to the full Collège de 'Pataphysique in 1961. In addition, Temps Mêlés (in French) devoted an issue to Oulipo in 1964, and Belgian radio broadcast one Oulipo meeting. Its members were individually active during these years and published works which were created within their constraints. The group as a whole began to emerge from obscurity in 1973 with the publication of La Littérature Potentielle, a collection of representative pieces. In 2012 Harvard University Press published a history of the movement, Many Subtle Channels: In Praise of Potential Literature, by Oulipo member Daniel Levin Becker.
