STEPS THAT THE LIBRARY CAN TAKE IN PREPARING FOR A CHANGE TO AN AUTOMATED SYSTEM WERE INVESTIGATED. THE METHOD DESCRIBED WAS BASED ON AN ANALYSIS OF CLERICAL AND OFFICE WORK CALLED INTEGRATED PROCEDURES OF CONTROL (IPC). THE APPLICATION OF LIBRARY SYSTEMS ANALYSIS (LISA) TO THE LEHIGH UNIVERSITY LIBRARY IS DESCRIBED. THIS PROCESS INVOLVED (1) DEVELOPING A GENERALIZED REPRESENTATION OF THE LIBRARY, (2) DEVELOPING AN EFFECTIVE MODEL OF THE LIBRARY, (3) DEVISING A STANDARD METHOD FOR COLLECTING DATA, (4) ASSIGNING CLASSIFICATIONS AND CODES FOR THE COLLECTED DATA, (5) REDUCING THE DATA TO PUNCHED CARDS, AND (6) DETERMINING WAYS OF EVALUATING THE PUNCHED CARD MODEL. THE INVESTIGATORS CONCLUDED THAT LISA SHOULD BE APPLICABLE TO MOST MEDIUM-SIZED ACADEMIC AND RESEARCH LIBRARIES. (WB)
