摘要:MLA committee membership by category (medical school, society and hospital) for the past three years is examined revealing a heavy reliance upon medical school librarians for committee members. A ten-year examination of committee membership and turnover in individual committee membership rosters points out those committees whose rate of turnover is greatest. Opportunities for service by new MLA members is examined as is committee tenure as experienced during the last decade. Turnover, tenure, and frequency of leadership is examined for the ten-year period. Pointing out that only 360 individuals have served MLA in committee positions listed in the Bulletin , the Ad Hoc Committee to Review the Goals and Structure of the Medical Library Association is urged to more actively seek the opinions of the membership and to consider the service patterns of the past in recommending a course for the future.
