There are several reasons why your Circulation activity report might return different results for the same time frame, depending on when you run the report:

  • Titles may have been returned at your library's request or recalled due to erroneous distribution (i.e., the publisher didn't have the rights to sell it) since the report was last run. When a title is removed from your collection for either of these reasons, any data related to the title (circulations, holds, etc.) is removed from reports.
  • If you're running the report for specific formats, you may be missing circulations where the format is "Pending." A "Pending" title has been borrowed but not yet downloaded (or opened in a browser) by the end user. Once the title is downloaded or opened, that circulation is then associated with the appropriate format (current and historical). When you run the report by format again, circulations previously shown as "Pending" may now be associated with the appropriate format and show up in your report.
  • If you're running the report by branch, and there were branch code changes since the report was last run, this can affect your results.
  • Advantage libraries: Advantage copies of consortium-owned titles may have been purchased for the first time since the report was last run.
    For example: An Advantage library runs the report and gets data for their Advantage collection. Later, the Advantage library purchases their own copies of consortium-owned titles. The historical checkouts made by their end users on the consortium-owned copies will now appear in the report, along with current checkouts, for all date ranges. So, even though the Advantage library didn't own the title when they first ran the report, the report would now include historical checkouts (by their end users) on that title.
