Book Catalogs Computer Output Microfilm Computers Diagrams History Interprofessional Relationship Printing Standards Subject Index Terms Technology Union Catalogs Early computers dealt with mathematical and scientific problems requiring very little input and not much output, therefore high speed printing devices were not required. Today with increased variety of use, high speed printing is necessary and Computer Output Microfilm (COM) devices have been created to meet this need. This indirect process can increase printing speed by 40 times, with uses including dissemination and documentation in service industries; micropublishing for economical reasons; creation of library book catalogs, where catalog information is converted into a machine readable data base produced by a commercial vendor with such advantages as shared costs; ease of conversion from ASCII (American Standard Code for Information Interchange) to EBCDIC (Extended Binary Coded Decimal Interchange Code) and interpretation of material; allowance in procedures and programs required to accommodate updating of records; and the capability of varied catalog formats. The advantages of COM, e.g., no filing errors, easy duplication and dissemination, and less required space, outweigh the disadvantages, e.g., the inability to withdraw a book record, time required to add new cataloging, the required use of two look up points, and the lack of cross references.
