1. Brinley Franklin Vice Provost, University of Connecticut Libraries MINES for Libraries Measuring the Impact of Networked Electronic Services (MINES): The North American Experience

2. MINES is a research methodology consisting of a web- based survey form and a sampling plan. MINES measures who is using electronic resources, where users are located at the time of use, and their purpose of use. MINES was adopted by the Association of Research Libraries (ARL) as part of the “New Measures” toolkit in May, 2003. MINES is different from other electronic resource usage measures that quantify total usage (e.g., COUNTER, EQUINOX, E-Metrics, ICOLC Guidelines, ISO and NISO standards) or measure how well a library makes electronic resources accessible (LibQual+ TM ). What is MINES?

3. Data was collected at 18 university libraries in Ontario, Canada (OCUL) between May, 2004 and April, 2005. Data was also collected at 14 university libraries in the United States between January, 2003 and April, 2005.

4. More than 50,000 networked electronic services uses in the U.S. were surveyed. At each U.S. library, the MINES survey was one component of a comprehensive cost analysis study that assigned all library costs to sponsored research, instruction/education/non- sponsored research, patient care, other sponsored activities and other activities. Recent Data Collection Activities MINES was also conducted by the Ontario Council of University Libraries (OCUL) in 2004-2005 in conjunction with ARL. More than 20,000 users were surveyed.

5. A representative sampling plan, including sample size, is determined at the outset. Typically, there are 48 hours of surveying over 12 months at a medical library and 24 hours a year at a main library. Random moment/web-based surveys are employed at each site. Participation is usually mandatory, negating non-respondent bias, and is based on actual use in real-time. Libraries with database-to-web gateways or proxy re-writers offer the most comprehensive networking solution for surveying all networked services users during survey periods.
