Why do we see a database that we don't subscribe to, listed on our Database Master report?

It may show up on both of your Database Master report and and Database Usage (DR_D1) usage reports. It may also show up on Database Access Denied (DR_D2) report.
This could be due to a user who tried to access that database belonging to a different institution and received a denial of license error message. 

If you don't see that database listed on Database Access Denied (DR_D2) usage report, please contact ProQuest Technical Support at technicalsupport@proquest.com
