The International Association of Libraries and Museums of the Performing Arts (French: Société Internationale des Bibliothèques et des Musées des Arts du Spectacle, abbreviated SIBMAS), promotes practical and theoretical research in the documentation of performing arts.
The association was founded in 1954, and has organized biennial international conferences since then, primarily in European cities.
Spread across 35 countries around the world, it gathers individuals and institutions documenting circus, dance, film, opera, theatre and puppetry.
The association is also concerned with ensuring the proper conservation of the performing arts collections.
At the beginning of 2021 it expressed its concern about the Victoria & Albert Museum's (V&A) intention to close the Department of Theatre and Performance.
