COUNTER Frequently asked questions

What does COUNTER mean?

COUNTER (Counting Online Usage of Networked Electronic Resources) is an initiative formed by libraries and publishers to provide consistent, credible and comparable usage reporting so as to help libraries understand how the information accessed from a variety of vendors/publishers is being used. To learn more about COUNTER, go to

How do I access my reports?

Your institutions reports can be found by going to the following URL:

Which journals are included in COUNTER reports?

All IOP journals and IOP ebooks are listed in the COUNTER reports, whether you subscribe or not. This is to allow you to see usage of open access titles, and other content that IOP makes freely available.

When should I expect monthly COUNTER reports to be updated?

The COUNTER standard requires that publishers deliver COUNTER Reports within one month. This means that the report containing usage data for January must be available to libraries by the end of February. MPS Insight aims to make reports available earlier than the one month maximum defined by COUNTER. You can opt to receive an email alert notifying you when your updated COUNTER reports are available each month – see the Email Alerts section when logged into your account in the MPS Insight interface.
