ARL New Measures MINES for Libraries Measuring the Impact of Networked Electronic Services Brinley Franklin Vice Provost University of Connecticut Libraries

What is Mines? Measuring the Impact of Networked Electronic Services (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 because most studies of electronic information usage have been related to usage counts (e.g., COUNTER, EQUINOX, E-metrics, ICOLC Guidelines, ISO and NISO standards) or how well a library makes electronic resources accessible (LibQual+TM).

Recent MINES Collection Activities Data was collected at seven main campus libraries and seven academic health science libraries, between January, 2003 and January, 2005. At each library, the real-time 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. More than 45,000 networked electronic service users were surveyed. MINES is also being conducted by the Ontario Council of University Libraries (OCUL) in conjunction with ARL in 2004-2005.

Questions Addressed by MINES How extensively do sponsored researchers use the new digital information environment? Are researchers more likely to use networked electronic resources from inside or outside the library? Are there differences in usage of electronic information based on the user’s location (e.g., in the library; on-campus, but not in the library; or off-campus)? How does purpose of use (e.g., sponsored research, instruction, patient care) differ between electronic services use and traditional library services (e.g., print collections, reference services, etc.)? What is a statistically valid methodology for capturing electronic services usage both in the library and remotely through web surveys? Are particular network configurations more conducive to studies of networked electronic services use?

MINES Methodological Considerations 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 is employed at each site. Participation is 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.
