ARL Statistics Interactive Edition
The ARL Statistics are available through an interactive edition on the Web, supplementing previously available data from
1992–1993. Maintained and supported by the Geospatial and Statistical Data Center at the University of Virginia, this site
offers researchers access to ARL Statistics with documentation.1
Note that currently the site is aging and tables have not been updated with the latest data. ARL Index data are
erroneous. Updated index data may be found at http://www.arl.org/stats/index/index.shtml. We do have plans to
migrate the site to a new platform at ARL during 2009–2010.
The site offers maps and graphics depicting library trends. The interactive pages also include options for regional
aggregates, customized samples of observations, simple rank order tabulations of data, and the ability to create ratios of
any two variables. These and other capabilities are located at http://fisher.lib.virginia.edu/arl/.
The ARL Statistics datafiles since 1908 can be retrieved in spreadsheet format from http://www.arl.org/stats/
The ARL Statistics and Measurement Program Web site is located at http://www.arl.org/stats/.

American Research Libraries,” IFLA Journal 27 (2001): 257–63.
