In the National Institute of Multimedia Education, a database system for audio-visual resources has been developed in order to effectively utilize available resources and data. JEMISS (Japan Educational Media Information Service System) is a bibliographical database for domestic educational media such as 16 mm films, video and slide materials, which involves statement of copyrights. JEMISS has been offered to universities and research institutions through the Science Information Computer Network System. On the other hand, 'Educational method and technology, including information equipments and application of instructional materials' has been newly introduced, which covers instructional design, educational media, information equipments such as computers. Therefore we have discussed practical use of JEMISS on information education in universities of teacher education. Then we have developed an instructional program to practice information retrieval and have confirmed that the program is of an advantage to the students.
