A methodology is described for an automatic design system initially defined in terms of logical processes or program modules. Processes and files are grouped and reorganized in such a way as to produce an optimal design with respect to a specific target machine. Performance criteria for the optimal design are defined in terms of transport volume…

The logic of the system presented in this report is divided into six parts for computer processing and manipulation. They are: (1) processing of Library of Congress copy, (2) editing of input into standard format, (3) processing of information into and out from the authority files, (4) creation of the catalog records, (5) production of the…
