The purpose of this research is to develop evaluation indicators for evaluating the social value of libraries and, for this, first of all, preliminary evaluation indicators were derived by analyzing comprehensively about 60 domestic and overseas papers which researched on the value of libraries. On the basis of the derived preliminary evaluation indicators, 11 experts were selected and the final evaluation indicators were developed by conducting Delphi survey three times. The final evaluation indicators are composed of five evaluation areas, which are the divided areas of the social value of libraries, such as the development of local communities, the linkage of local communities, the improvement of local residents’ life quality, the equalization of local residents, and the information services necessary for local communities, 13 evaluation items, and 64 evaluation indicators. In the future, it seems that researches to measure the social value of libraries based on this will have to be conducted.
