4.0 Measuring and Assessing Reference Resources – Use, Usability, and Collection Assessment
As reference collections grow in size and format, there is an increasing need to assess their appropriateness, strengths, weaknesses, balance, and accessibility. Reference collections, both print and electronic, must be constantly assessed to determine their usefulness and relevancy to library patrons. Use and usability tests examine how often and how well visitors navigate, understand and use web sites, electronic subscription databases, free Internet resources, library subject web pages, and other web-based tools such as bibliographies, research guides, and tutorials.
Print Reference Resources
- In-Library Materials Use (Van House, Weil, McClure, 1990). Use to determine total number of items used in the library but not circulated. The Reference Assessment Manual, 1995.
- Reference Collection Use Study (Arrigona, Mathews, 1988). Use to evaluate which subjects areas are most used by librarians to assist patrons and then identify any correlation with the subject areas most used by patrons to answer their own questions. The Reference Assessment Manual, 1995.
- Strother’s Questionnaire A and B (Strother, 1975). Use to determine faculty awareness and use of reference tools The Reference Assessment Manual, 1995.
Web-based Reference Resources
- Formal Usability Testing – Observe as patrons use a site to perform given tasks or achieve a set of defined goals.
- Inquiry – Use interviews, surveys, and focus groups to gather information about patron preferences and use of a particular site.
- Inspection – Use to evaluate a site against a checklist of heuristics and design principles or simulations of typical user tasks.
