About the Preservation Directorate
The Library of Congress offers users a universal collection of ever-increasing diversity and scope. The Preservation Directorate sustains and ensures long-term access to these unmatched collections by evaluating, managing, and responding to the risks and challenges associated with the wide variety of materials in the Library’s care.
Organization of the Preservation Directorate
The work of the Preservation Directorate is carried out by four divisions (see also the Preservation Directorate Organizational Chart).
Collections Management
The Collections Management Division is responsible for inventory control, collections security, and space management for tens of millions of collection items across three Capitol Hill buildings and the Library’s off-site facilities, including the environmentally optimized preservation repository in Fort Meade, MD.

History of the Preservation Directorate
Thanks to the real threat of fire (and the devastation of the Library from fires in 1814 and 1851) the Library's preservation concerns extend far into the Library's history. Preservation activities grew organically throughout the first two-thirds of the 20th century, and the Library established the Preservation Office (now Directorate) in 1967, six months after the November 1966 flood in Florence that damaged more than one million books.
