Libraries are constantly under pressure to reduce content spending. In order to meet this challenge while continuing to serve their user’s real needs, the library needs to develop a deep understanding of content use across the organisation. This means augmenting plain usage data with details of organisational structure, and using that knowledge to choose optimal license and access strategies. By taking analytics a step deeper and leveraging a broad portfolio of access options, libraries can continue to support the research process while managing costs. We will discuss the challenges of aggregating usage data, demonstrate a selection of analytical tools, and how the analysis can inform the buy decision as well as the justification (ROI) for it. Attendees will gain an overview of analytical techniques, learn about the trade-offs of build vs. buy strategies, and come away with an understanding of key success factors for implementing an analytics program.
