ABSTRACT
This study draws from a variety of data sources (Appendix 1), but it is based on two unpublished data sets collected by the Association of Research Libraries ( A R L ) . 2 These data sets, compiled from A R L ' s 1990 and 1994 salary surveys, contain basic demographic data, including age, for librarians employed in A R L ' s 108 university member libraries. This study examines the shape and movement of the age profile of A R L librarians and attempts to identify the factors associated with each. The 1990 and 1994 A R L data are used to project changes in the population through 2020. Finally, the study addresses the age distribution of subgroups of the A R L population, to compare, for example, the age profile of reference librarians to that of cataloged, the age profiles of racial groups and age profiles by region.
