International Association of Libraries and Museums of the Performing Arts
The International Association of Libraries and Museums of the Performing Arts (, 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.

Institutional members include universities, libraries, and museums in 29 countries.

SIBMAS is engaged in three permanent projects:
 The World Directory on Theatre Museums and Libraries
 The International Bibliography of Theatre 
 The World Encyclopedia of Contemporary Theatre, in six volumes

Also sponsored is the online International Directory of Performing Arts Collections and Institutions, a list of over 7,000 institutions with material relating to the performing arts.

The association is governed by a 16-member international executive committee.
