Investigation and Comparison of Relative performance of institutional and participatory libraries

In the medium-term plan of improvement and development of public library, one of the key roles is the promotion of public participation's level. With this approach, this paper attemps to compare the relative performance of institutional and participatory public libraries. The method of this study is a descriptive- analytical method. Six input and three output indexes are extracted from statistical documentat. The statistical population is all provinces of Iran in 1389 and 1390. In addition, data envelopment analysis model is used for calculating of performance. The results show fixed position of Sistan Baloochestan and Hamedan in the top of performance province's list in participatory libraries and fixed position of Yazd, Azarbayjan Gharbi and Fars at the bottom of performance province's list in institutional libraries. Khorasan Jonoobi, Sistan-O- Baloochestan, Ilam and semnan have appropriate rank in overall. The changes are a sign of good management's deficiency in participatory libraries. The main reason of this result can be the yongness of these libraries. In general, it can be said that the participatory libraries are not stable structurally and organizationally yet; however, they are more efficient than institutional libraries.
