Standards for stats evaluating eresource usage. "The use of online information resources is growing rapidly. It is widely agreed by producers and purchasers of information that the use of these resources should be measured in a more consistent way. Librarians want to understand better how the information they buy from a variety of sources is being used; publishers want to know how the information products they disseminate are being accessed. An essential requirement to meet these objectives is an agreed international set of standards and protocols governing the recording and exchange of online usage data. The COUNTER Codes of Practice provide these standards and protocols and are published in full on this website."
