"The Niels Bohr Library & Archives and the Center for History of Physics are divisions of the American Institute of Physics that share a common mission: to help preserve and make known the history of modern physics and allied sciences. They work as one unit to develop and maintain an international, cooperative strategy that places the papers of physicists and allied scientists and the records of their programs at the most appropriate repository and to make information on these resources accessible through our ICOS, international Archival Catalog."
