There are two report options available to help you manage your reviews and acquisitions processes.
All Reviews report
The All Reviews report displays all reviews that have been requested, started, completed, and archived across your tenancy. The report is not a distinct list, therefore a review may appear several times dependent on the number of times the list has been reviewed. The report can then be refined using the available filters. Please see this article for more detail.
When you are in the list review itself you can now select to export the data out to a CSV file. This file will allow you to see the outcomes you have set, all notes to the library and to students.
