This plan for the development of Montana library service is based on the experiences of other states, opinions of library experts, written information on Montana libraries, visits to several libraries, and attendance at meetings of the Montana Library Association and its committees. Specific recommendations include: moving the State Library headquarters to Helena; evaluating existing libraries in relation to established standards; instituting new legislation and repealing out-of-date library laws; cooperative programs among libraries for effective use of staff; job descriptions and pay scales; additional staff for most libraries; increases in salaries; a recruiting and scholarship program; an enlarged, state-wide program of in-service training; determination of an effective, state-wide program of minimum library service; identification of all possible sources of funds; interpretation of the value of library service to the public; an increase in appropriations for the Montana Library Commission and establishment of state aid for public libraries; and enlisting the aid of government officials, organizations and civic-minded citizens in developing effective library service.
