The Rutgers University Library's Annex, a compact library storage facility opened in 1982, is designed to house approximately one-half million volumes of varying sizes, including monographs, serials, and containerized items in permanent storage boxes. By using the high density, economical storage at the annex for little-used library materials, space is made available in the university's library buildings for more frequently used materials. Even though materials have been relocated to the annex they continue to be available for either on-site patron use or more commonly, for delivery to another university library. This procedures manual describes the physical layout of the building, stack organization, the cataloging system used in the annex, selection criteria for materials to be stored at the annex, circulation policies, and patron facilities and services.
