Striving for Uniqueness: Data-Driven Database Deselection

Mercer University Libraries consist of three main entities that have historically subscribed to electronic resources separately. The libraries will begin the process of consolidating access and subscribe to resources as a single body, providing a consistent set of resources to students across Mercer's wide geographic area. In order to accomplish this we will need to reduce the number of aggregated databases to be able to share access to the remaining titles at all locations without increasing the net fiscal outlay.

This presentation will introduce the title comparison tool that the Library Systems Department has developed to inform decisions that subject bibliographers and selectors must make. Existing tools for overlap analysis tend to focus exclusively on full text access, but our investment in indexes is significant, necessitating a closer look at their uniqueness and ongoing value to our institution. Our tool presents vital data including the uniqueness of titles within each database as compared to all other databases about which we have information. We will discuss the process that we followed to ingest vendor-supplied title lists, the challenges that we encountered in normalizing data and conceptualizing the overlap analysis, and the data model that we settled upon to produce quick, interactive results.

The audience will be encouraged to participate in the presentation by asking questions or sharing their own experiences throughout via either social media or conventional means.

Attendees can expect to learn about the process of developing in-house software to aid in vital data-intensive collection management tasks. They will also gain insight into the process and pitfalls of detecting duplication among title lists for a large number of databases.
