There are more than 320,000 public libraries around the world. Adding to this figure are thousands of academic, government, research, museum, ecclesiastical, special topic, film, and home libraries. The largest libraries on the planet, such as the Library of Congress and British Library, house more than 15 million books, artifacts and archived materials each. A single incident of water damage in libraries can prove financially catastrophic, especially if the items affected are numerous, valuable or rare. When libraries pair climate control solutions with archival best practices and emergency preparedness, they reduce the need for water-damaged-book restoration and make a valuable investment in the institution’s future.
