About The Data

  • In the first graph, data come from JR1 Counter reports provided by publishers.  JR1's provide include successful number of full text article requests(downloads) by month and journal title.
  • JR1s don't differentiate downloads by publication date or publication archive.  For those totals, please ask to see Counter Reports JR5 and JR1a.
  • CTS retrieves approximately 135 JR1s every 6 months so that both annual and fiscal year totals can be provided to outside agencies and university stakeholders.
  • We report JR1 totals to ARL, ASERL, ACRL, and IPEDS, where they are typically referred to as "total successful article requests."
  • In the yearly graph, totals are for annual years rather than fiscal years.  Annual year and fiscal year totals will differ.
  • ARL and Anuual totals will be different. ARL collects totals for the period July 1 - June 30 rather than annual totals
