Speaker: Anne Prestamo
You will not hear the magic rational that will allow you to cancel all your A&I databases. The last three years of analysis at her institution has resulted in only two cancelations.
Background: she was a science librarian before becoming an administrator, and has a great appreciation for A&I searching.
Scenario: a subject-specific database with low use had been accessed on a per-search basis, but going forward it would be sole-sourced and subscription based. Given that, their cost per search was going to increase significantly. They wanted to know if Summon would provide a significant enough overlap to replace the database.
Arguments: it’s key to the discipline, specialized search functionality, unique indexing, etc… but there’s no data to support how these unique features are being used. Subject searches in the catalog were only 5% of what was being done, and most of them came from staff computers. So, are our users actually using the controlled vocabularies of these specialized databases. Finally, librarians think they just need to promote these more, but sadly, that ship’s already sailed.
Beyond usage data, you can also look at overlap with your discovery service, and also identify unique titles. For those, you’ll need to consider local holdings, ILL data, impact factors, language, format, and publication history.
Once they did all of that, they found that 92% of the titles were indexed in their discovery service. The depth of the backfile may be an issue, depending on the subject area. Also, you may need to look at the level of indexing (cover to cover vs. selective). In the end, they found that 8% of the titles not included, they owned most of them in print and they were rather old. 15% of the 8% had impact factors, which may or may not be relevant, but it is something to consider. And, most of the titles were non-English. They also found that there were no ILL requests for the non-owned unique titles, and less than half were scholarly and currently being published.
