I was asked by a colleague here at University of the Arts London: "Is there any easy way to track usage on titles highlighted on the coverflow, during the display period? So [we could track] borrowing or reservations for print titles, and clicks out to the platform for online ones?"

This should be possible with Matomo web analytics platform
