| Abstract: | Summaries. The size and complexity of preservation problems facing research libraries call for institutional cooperation. In the 1960s, specific needs of a national preservation effort were identified and these needs have remained the bases of discussions up to the present time. Initially, there was an assumption that most of the identified needs would be met and solved at the national level by a centralized agency- most frequently mentioned was the Library of Congress. What, in effect, has developed is a national preservation effort on the part of the Library of Congress that provides both direct and indirect services to the library, archive, and preservation communities. Research and fabrication developments carried out at the Library have contributed to the national effort and will continue to do so in the future, but local and regional planning and cooperation are essential, if a national program is to be realized. |
