COUNTER statistics are an integral part of evaluating the acquisition of electronic resources in libraries. The eUsage app is a tool to facilitate the seamless inclusion of usage statistics into the ERM processes within FOLIO. It supports automatic monthly harvesting of statistics from providers offering SUSHI APIs, as well as manual upload for providers that do not. It interacts with the agreements app, connecting an electronic resource agreement directly with the associated statistics. This enables many advanced features: filtering the COUNTER data according to the agreement’s actual holdings, getting finance information and calculating cost per download statistics, displaying preview statistics and graphs directly with the agreement and many more.
