Intended for use by library staffs, directors, and trustees, this report of salary and staffing information for Massachusetts public libraries for 1978 is presented in a standardized format to facilitate the identification of comparable libraries and the comparison of salaries and other personnel data. Explanatory notes define the terms used in the tables. Section I contains salary and staffing reports for individual municipalities, arranged in seven population groups, based on the 1975 state census. Salary ranges shown are those paid library employees on July 1, 1978 or for fiscal year 1979. Section III offers a series of three summary tables, for each of which data are presented by population group and regional affiliation: (1) high, average, and low maximum salaries for selected positions; (2) distribution of educational levels for employees of reporting libraries; and (3) fringe benefits for employees of reporting libraries. The report concludes with two public library personnel report questionnaires used to gather the data--one for municipalities under, the other for those over, 5,000 population. Both include instructions. (JD)
