The purpose of 70-649 preservation is to ensure protection of information of enduring value for access by present and future generations (Conway, 1990: 206). Libraries and archives have served as the central institutional focus for preservation, and both types of institutions include preservation as one of their core functions. In recent decades, many major libraries and archives have established formal preservation programs for traditional materials which include regular allocation of resources for preservation, preventive measures to arrest deterioration of materials, remedial measures to restore the usability of selected materials, and the incorporation of VCP-310 preservation needs and requirements into overall program planning.
Preservationists within the library and archival community have been instrumental in developing an array of tools and methodologies to reduce the decay of traditional materials and to restore books and documents that have deteriorated to such an extent that their longevity and usability are threatened. Provisions for fire protection and adequate environmental controls frequently are incorporated into new library and archival facilities. Rehousing of acid-based VCP-101V paper materials is a common task in many repositories and microfilming is used extensively and cost effectively to preserve endangered materials.
