Abstract

It will not be an easy task to automate the Library of Congress Classification schedules because it is a very large system and also because it developed long before automation. The designers were creating a system for shelving books effiently and had not even imagined the constraints imposed by automation. A number of problems and possible solutions are discussed. The MARC format proposed for classification has some serious problems which are identified
