Microfilm for the Library of Congress

Charles G. La Hood
1973 College and Research Libraries  
In 1969 alone, the Library of Congress produced more than 11.3 million individual microfilm exposures on negative film. More than 5.6 million feet of positive print film were made from these and other negatives. Microfilming has been used to solve the need for storage space; to preserve newspapers and rare and fragile documents; to produce copies for outside orders; to conserve copyright records; and to acquire new materials for the Library collections.
