From the “Call” Document (via SCONUL):
We write as representatives of the international academic library community to urge library content providers to prioritise and expedite a transition to Release 5 of the COUNTER Code of Practice, which became effective in January 2019.
COUNTER’s members contributed to the development of Release 5 (R5) of the COUNTER Code of Practice, which enables content providers to produce consistent, comparable and credible usage data for online content. This allows librarians and others to compare the usage data they receive, and to understand and demonstrate the value of the electronic resources to which they subscribe.
Those providers offering usage data solely under Release 4 of the Code of Practice are no longer COUNTER compliant. Compliant COUNTER Release 5 providers are listed on the COUNTER website. As a community that licenses content from a wide range of providers, COUNTER Release 5 compliance by all our providers is critical to informing decisions and stewardship of our funds.
