The Times Literary Supplement (TLS) has served for over 100 years as a leading forum for fine writing, literary discoveries, and insightful debate. The weekly review was founded in 1902 as a free supplement to The Times (London), and it became a separate publication in 1914. From its Anglo-centric beginnings, it developed into a truly international publication by the mid-twentieth century, with contributors from every region of the world and coverage ranging from literature and criticism to history, science, politics, and art.

Until 1974, writings and influential criticism by hundreds of the twentieth century's most important writers and thinkers were kept anonymous to foster open discussion. The Times Literary Supplement Historical Archive now discloses the identity of these contributors.
