In December 2001, The International Coalition of Library Consortia (ICOLC) issued an update to its guidelines concerning the metrics used in evaluating electronic journal and database usage. ICOLC focuses primarily on defining what publishers need to report regarding the usage of electronic content and database searching. The updated "Guidelines for Statistical Measures of Usage of Web-Based Information Resources" (Update: December 2001) clarifies these requirements for reporting library usage of vendor systems.
Elsevier Science has undertaken to support the updated ICOLC Guidelines and hence ScienceDirect Customer Usage Reports will be compliant with these ICOLC Guidelines in all future report upgrades. Elsevier Science has been actively involved with the development of published industry guidelines and intends to continue to work with ICOLC to publish further updates to the published guidelines, which focus on the reliability and standardization of the reported data and underlying metrics. Initially Elsevier Science will exchange its definitions of the reported data-elements, metrics and supporting systems with ICOLC, a crucial starting point in determining standard ways of reporting usage. In addition, Elsevier Science will commission an official audit of ScienceDirect metrics and reports in 2002.
The complete original and updated Guidelines with endorsing library consortia and additional information about the ICOLC can be found at http://www.library.yale.edu/consortia. These Guideline updates are each initially endorsed by 70 library consortia from around the world. More consortia endorsements are added to each as received by the ICOLC.
About ScienceDirect Customer Usage Reports
Every month librarians and information managers receive ScienceDirect usage reports for their institution, which show the activity of their users. Metrics are available for article usage per journal (subscribed and non-subscribed), searching, sessions, number of active users and many more items. With a 13-month reporting window it is very easy for customers/librarians to distinguish usage trends. To view a demo version of the reports please logon to:
