COUNTER - Counting Online Usage of NeTworked Electronic Resources
COUNTER has been developed to provide a single, international, extendible Code of Practice that allows the usage of online information products and services to be measured in a credible, consistent and compatible way using vendor-generated data. [...] In response to librarian demand, Release 1 of the COUNTER Code of Practice focuses on the usage of journals and databases, the products that account for the largest share of most libraries' materials budgets.
