This study attempted to analyze the collection management process and its requirements for public libraries. The survey was designed to examine the detailed collection management guidelines and to grasp its requirements varying across different types of public libraries. The respondents to the survey were librarians who are responsible for managing collections in public libraries which achieved excellence in the 2008 nationwide library management assessment. The study results indicated that most public libraries do not have organized collection management guidelines covering the whole collection management area. In addition, small libraries such as those in hospitals, armies, and prisons have difficulties in managing collections since they do not have proper collection management guidelines.
