56. Material Retention

Regional depository libraries must receive and retain at least one copy of all Federal government publications made available under the FDLP in printed form, microfiche, or tangible electronic (e.g. DVD) format. Regional libraries may discard depository materials that have been authorized for regional discard by the Superintendent of Documents, such as superseded items, or those later issued in bound form. A Selective Housing Agreement between the regional library and another depository library is a mechanism to ensure that a tangible copy is available if a regional library is not able to maintain the tangible collection in a library facility under their library administration.
