Abstract
A prototype expert system for the computer science section (QA75 to QA76.95) of Library of Congress Classification was built using the Mahogany Professional expert system shell. The prototype demonstrates an expert systes application in which the system is enlisted as an intelligent job aid to assist users during the actual performance of shelflisting
