From 1 January 2014 only those Vendors and Usage Reports included in this Register may be considered to be COUNTER compliant.

Publishers and vendors must undergo an independent audit in order to comply with the COUNTER Code of Practice Release 4. When COUNTER receives a successful audit report, the publisher or vendor is listed below as an Audited Entity.  SUSHI details for an Audited Entity can be found by clicking on their entry below.

COUNTER audits can cover many publisher platforms supported by an Audited Entity. If we have received specific SUSHI details for these publishers, they can be found under the Supported Publisher Platforms list. If we have not received specific SUSHI information, and you cannot see a publisher on either of the lists below, type its name in the search box to find if it is covered by an Audited Entity.
