ARL Index Data

This section is based on the five variables used to determine the ARL index scores for each institution (volumes held, volumes added (gross), current serials, total expenditures, and total professional plus support staff), and the ARL index score. Use this part of the site to create a report displaying all of these variables for individual institutions (1986 forward); to display a ranked report of any one of the six variables for any number of institutions for a single year; to produce a graph of the variables for one institution from 1986 to the current year; or to graph one variable for up to nine institutions. Visit the ARL site for more information on the ARL Membership Criteria Index.
