4. What is MINES?
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).

Collection Activities
Data was collected at seven main campus libraries and seven academic health science libraries in the U.S., between January, 2003 and January, 2005.

6. Collection Activities
Recent Data
Collection Activities
More than 45,000 networked electronic
services uses were surveyed.
At each 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.
MINES is also being conducted by the Ontario Council of University Libraries (OCUL) in in conjunction with ARL.

7. Questions Addressed
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)?
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 digital libraries patron use?

8. 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 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.
