The purpose of this study is to apply the international quality certification system to service quality evaluation in library and information service centers. The study compared various aspects of their quality certification systems and considered application studies of foreign libraries. The results of this study illustrate that TQM based quality certification systems-Deming Quality Prize, Malcolm Baldrige National Quality Awards, European Quality Awards-reflects a broader, more dynamic and custome-oriented quality concepts. On the contrary, ISO 9000 Standards are based on a narrow, static and in house-oriented quality concepts emphasizing conformance to specifications.
