Article 29 in the copyright law of Korea, public performance and broadcasting for non-profit purposes will be revised. The copyright agency has tried to impose copyright fees on the use of cinematographic works such as DVDs in public libraries. The paper studied that the individual watching cinematographic works in public libraries is included in the concept of public performance in the copyright law. Also, the study conducted a survey on the situation of use of cinematographic works in public libraries. As a result of the study, watching DVDs in facilities for 1~3 persons in public libraries could be included in the concept of public performance. But the main purpose of most of DVD users was for circulation or reading. The library service for individual DVD watching will therefore not affect the commercial income of the copyright holders. Finally the study suggested that if the service for the individual watching of cinematographic works in libraries is included in the concept of public performance, the copyright law needs to be revised so that the service is included in the exception to the right of public performance.
