Due to the special conditions of public libraries, especially after their reorganization under the Board of Trustees of the Public Libraries (BTPL), and the necessity for re-organization of and re-planning for libraries and librarians, it is necessary for managers of the BTPL to identify and illustrate the present status of libraries and librarians to be able to proceed with their planning. Benefiting the opportunity provided by a short term course for librarians of four provinces of Khuzestan, Booshehr, Fars and Kohgiluye in which the present authors were involved, a survey based on the Job Description Index (JDI) was devised and administered to assess the degree of job satisfaction among the target librarians in terms of: supervision, co-workers, payments and promotion as well as general job satisfaction. Results of the study revealed that all librarians, despite their dissatisfaction in regards with some aspects, especially payments and promotion, were all satisfied with their job as librarians. Running an ANOVA test with repeated measures indicated existence of no significant difference among the mentioned variables, except for payments. However, running the post-hoc test of Tukey’s HSD revealed that the difference lies between Khuzestan librarians and their colleagues in other 3 provinces. The data collected revealed no significant difference among other groups of librarians. Due to other disorders observed in relation with status of librarians in terms of their distribution age-wise, while suggesting the decision makers to review the librarians’ payments and promotion schemes, it is suggested that decision makers plan and act in regard with recruit of younger librarians before the older librarians are retired, and allow some time for them to transfer their knowledge and methods of job administration and techniques to younger ones.
