Additioansl qualities and skills which the catalogers in this environment will need are indentified. The review is done through the examination of research reports and results of numerous library surveys. The overall climate of change is toward a process of conver gent evolution between catalogers and public service librarians. The heads of technical services departments and several catalogers in eight Korean academic libraries including National Central Library are interviewed to find out the present development of automation and any effect on cataloging staff in terms of work and organizational structure.
