A complex tool, data envelopment analysis (DEA) was used to evaluate the relative efficiency of major academic research libraries that are members of the Association of Research Libraries (ARL). Results of a two-year base line study using traditional measures taken from 1995-96 ARL statistics are reported. (AEF)

Discusses the ARL (Association of Research Libraries) E-Metrics project that is investigating problems related to collecting and using data for electronic materials and services. Describes a survey of libraries that focused on data collection activities and showed a lack of preparation as well as a lack of consistent statistics from database…

This study applied an analytical technique called Data Envelopment Analysis (DEA) to calculate the relative technical efficiency of 95 academic research libraries, all members of the Association of Research Libraries. DEA, with the proper model of library inputs and outputs, can reveal best practices in the peer groups, as well as the technical…

Presents a model of the relation between the circulation at a large library, the collection at that library, and the size of the user population. Analysis of data at United States academic research libraries reveals a square-root law describing this relation. Explores theoretical foundations and speculates on bibliometric implications.

Describes a new analytical tool, data envelope analysis (DEA) model, which can provide better understanding of the efficiency of academic research libraries. Reports the results of a study using 1994-1995 Association of Research Libraries statistics together with expert judgments, in terms of constraints, to make the model more applicable to the…
