A study was done of salary determinants for academic librarians in light of the increasing trend to include academic and librarian faculty in joint bargaining units for compensation. The study analyzed position, gender, faculty status, rank, tenure, experience, and academic preparation as salary determinants for 469 librarians at 25 state colleges and univerisities. The main findings of the study were that higher librarian salaries were associated with completion of an advanced degree, attainment of an administrative position, and longer years of service. For librarians employed at university institutions, faculty status and rank were of more influence on salaries than for those working at the state colleges. Faculty librarians earned significantly less than academic faculty at the same rank. These findings prompted recommendations for benchmarking librarian salaries, and for treating most librarians as members of a single discipline. Included are 1 figure, 4 tables, and 21 references.
