NASIG 2012: A Model for Electronic Resources Assessment

Presenter: Sarah Sutton, Texas A&M University-Corpus Christi

Began the model with the trigger event — a resource comes up for renewal. Then she began looking at what information is needed to make the decision.

For A&I databases, the primary data pieces are the searches and sessions from the COUNTER release 3 reports. For full-text resources, the primary data pieces are the full-text downloads also from the COUNTER reports. In addition to COUNTER and other publisher supplied usage data, she looks at local data points. Link-outs from the a-to-z list of databases tells her what resources her users are consciously choosing to use, and not necessarily something they arrive at via a discovery service or Google. She’s able to pull this from the content management system they use.

Once the data has been collected, it can be compared to the baseline. She created a spreadsheet listing all of the resources, with a column each for searches, sessions, downloads, and link-outs. The baseline set of core resources was based on a combination of high link-outs and high usage. These were grouped by similar numbers/type of resource. Next, she calculated the cost/use for each of the four use types, as well as the percentage of change in use over time.

After the baseline is established, she compares the renewing resource to that baseline. This isn’t always a yes or no answer, but more of a yes or maybe answer. Often more analysis is needed if it is tending towards no. More data may include overlap analysis (unique to your library collection), citation lists (unique titles — compare them with a list of highly-cited journals at your institution or faculty requests or appear on a core title list), journal-level usage of the unique titles, and impact factors of the unique titles.

Audience question: What about qualitative data? Talk to your users. Does not have a suggestion for how to incorporate that into the model without increasing the length of time in the review process.

Audience question: How much staff time does this take? Most of the work is in setting up the baseline. The rest depends on how much additional investigation is needed.

[I had several conversations with folks after this session who expressed concern with the method used for determining the baseline. Namely, that it excludes A&I resources and assumes that usage data is accurate. I would caution anyone from wholesale adopting this as the only method of determining renewals. Without conversation and relationships with faculty/departments, we may not truly understand what the numbers are telling us.]
