Measures for Electronic Use: The ARL E-Metrics Project

Libraries are spending a larger proportion of their materials budget on electronic resources. In 2001, members of the Association of Research Libraries (ARL) spent more than $132 million on electronic resources. In order to determine if their dollars are being well spent, 24 members of ARL self-funded a research project to develop measures for describing the resources, expenditures, and usage of electronic resources. The project resulted in a set of recommended measures and a data collection process that will continue to be refined and tested by ARL members.
