Longitudinal growth and use of Open Repositories in the U.S. since 2015

One indication of the maturity of institutional repositories (IRs) in 2015 was that the Association of College and Research Libraries (ACRL) added two questions focused on IRs to their Academic Library Trends and Statistics Survey. ACRL has continued to collect this data annually, documenting the number of IR items and downloads. This lighting talk will take a longitudinal dive into this data for a quantitative IR portrait of the past decade and include the type of U.S. higher education institution as defined by Carnegie classification. By looking at this self-reported data from the past decade, growth trends and benchmarks can be observed along with ongoing questions of the various complexities in measuring IR success. Models can also be built on this past record to anticipate future capacity needs for the IR ecosystem.
