- The ARL Library Index and Quantitative Relationships in the ARL. Stubbs, Kendon College Libraries Correlation Evaluation Criteria Factor Analysis Graphs Group Membership Higher Education Institutional Characteristics Library Collections Library Expenditures Library Personnel Regression (Statistics) Research Libraries Tables (Data) In order to explain the derivation and implications of the Association of Research Libraries (ARL) Library Index (a descriptive statistical indicator of research library quality which is based on an analysis of certain key library characteristics), this paper discusses regression and correlation as methods for measuring relations between such variables as size of professional library staff and size of library collections, and describes the use of factor analysis to identify major characteristics common to ARL members. A summary of the techniques of regression and factor analysis is given. Data provided include a table listing ARL members' Library Index scores for 1978-1979, an overview of trends in ARL Library Index scores from 1969 to 1979, and a set of 75 graphs illustrating fluctuations in individual ARL members' Library Index scores from 1969 to 1979. An explanation of the calculation of principal Library Index component scores, and notes on the text are appended. (JL)
