Istanbul Topkapi Palace, Hagia Sophia archive and Suleymaniye Library hold millions of irreplaceable manuscripts. The 2019 Notre-Dame and 2004 Weimar Anna Amalia fire destroyed 50,000 books. NFPA 909 mandates pre-action sprinkler, water mist and VESDA early smoke detection for museums and libraries.
