One of the specific recommendations in the Retrospective Conversion (RECON) feasibility report (ED 032 895) was that a pilot project be established to test various conversion techniques, ideally covering the highest priority material (English-language monograph records from 1960-68). A two-year pilot project was initiated in August 1969. This report is oriented toward the work of the project as a whole. The pilot project conducted at the Library of Congress covered five major areas: (1) testing techniques postulated in the RECON report in an operational environment, (2) development of procedures and computer programs to implement format recognition, (3) analysis of techniques for the conversion of older English-language materials in foreign languages using the roman alphabet, (4) monitoring the state-of-the-art of input devices that would facilitate conversion of a large data base, and (5) a study of microfilming techniques and their associated costs. The accomplishments of the pilot project are discussed in detail in this document. (Author/SJ)
