Jointly published by IMO and the International Civil Aviation Organization (ICAO), the three-volume International Aeronautical and Maritime Search and Rescue (IAMSAR) Manual provides guidelines for a common aviation and maritime approach to organizing and providing search and rescue (SAR) services. Each volume can be used as a stand-alone for conjunction with other volumes. Mission Co-ordination (volume II) assists personnel who plan and co-ordinate SAR operations and exercises.

The 2022 edition incorporates amendments adopted by ICAO and approved by the IMO Maritime Safety Committee. The 2021 amendments enter into force on 1 June 2022.
