This year in the statistics that we report to CAUL there is a new category  for ejournal use.    This statistic includes the use of gold open access articles.

There is a COUNTER report (JR1 GOA) that we can run to get the gold usage.

We have run reports for our main publishers/providers and they show that gold articles were downloaded 46,657 times by UC users in 2017.

The Counter reports are available here
