Usage: COUNTER Statistics:
In April 2014 we launched our new usage portal to provide institutional customers with COUNTER 4-compliant usage reporting.
The COUNTER 4 code of practice provides an international, extendible Code of Practice for e-Resources that allows the usage of online information, products, and services to be measured in a credible, consistent, and compatible way using vendor-generated data.
COUNTER reports are released on a monthly basis and are available for Online resources and Journals.
