The Bibliothèque de la Pléiade ([bi.bli.j .t k d la ple.jad], "Pleiades Library") is a French series of books which was created in 1931 by Jacques Schiffrin, an independent young editor. Schiffrin wanted to provide the public with reference editions of the complete works of classic authors in a pocket format. André Gide took an interest in Schiffrin's project and brought it into Gallimard, under which it is still published.
The Pléiade has a strong emphasis on works that were originally written in French, though the collection also includes classics of world literature, such as bilingual editions of the works of William Shakespeare, or French editions of Jane Austen's work. To date, more than eight hundred books have been published in the series, with eleven books generally published every year. The "entry into the Pléiade" is considered a major sign of recognition for an author in France, and it is extremely rare that a living author is published in the Pléiade.

All the books offer a similar high quality appearance leather bound, with gold lettering on the spine and bible paper, and they have a practical small format which makes them look like small Bibles. The use of bible paper allows the books to contain a high number of pages; it is common for a Pléiade book to contain at least 1500. The longest volume in the Pléiade is Les mille et une nuits I, II et III, at 3504 pages.
