About the Repertoire

The Repertoire, mandated by the General Assembly in resolution 686 (VII) in 1952, provides comprehensive coverage of the Security Council’s interpretation and application of the United Nations Charter and its own Provisional Rules of Procedure since 1946. Its primary purpose is to provide Member States, including those elected to serve on the Security Council, the United Nations system, academics and others with a source of information regarding the evolving practice of the Security Council.
