  • Uses scripts that update on the first of each month and leave out shadowed items and locations
  • Member sites were asked which item types they use for each IPEDS field; results are pre-filtered here to reflect those choices
  • Uses ILLiad Borrowing - - Fill Rate Stats and Lending - Fill Rate Stats for each individual site


[1] EBSCO and LexisNexis Collection and Circulation counts automatically exclude Gold OA titles. It is not possible to include OA Access_Types for EBSCO or LexisNexis titles. Learn more about Gold Open Access from Open Library of Humanities.

[2] Data types have been pre-selected for SIRSI Workflows data based on institutional preferences.

[3] LexisNexis is not COUNTER compliant and instead uses "retrievals by source"

[4] Totals are calculated using the COUNTER 5 metric Total_Item_Investigations (LearningExpress PrepStep uses Sessions; OCLC FirstSearch uses Searches).

[5] Note that IPEDS does not request inclusion of databases in Digital/Electronic Circulation counts. These numbers are included for your own data-keeping purposes.
