Effective Nov 10th, researchers can export up to 20,000 search results, up to 10 times per day on the ProQuest platform. Previously, researchers could export only up to 10,000 results, twice per day, causing a great deal of frustration for those conducting systematic reviews.
In order to export results, researchers need to be logged into their My Research account. Instructions on how to do this is provided in the Support Article How can I export all my search results in ProQuest.
