Academic Libraries Comparative Analysis Data Analysis Higher Education Library Personnel Library Surveys Medical Libraries Research Libraries Science Libraries Discusses and analyzes information on personnel, gate count, and hours of operation in ARL (Association of Research Libraries) academic science and technology libraries for 1992-93. Data are then compared to similar data taken from the survey of academic health-sciences libraries, and potential comparisons with other library surveys are briefly mentioned. (Author/LRW)
