The document discusses a study on the value of libraries that aimed to investigate the relationship between library provision, usage, and research outcomes across UK universities and departments. The study objectives were to examine the characteristics of library services and resources provided to researchers, including volumes and types of content as well as services, and to analyze changes in these characteristics and key research performance indicators over the past decade in order to assess any correlations between library provision and research performance. The document notes some issues with determining value and demonstrating causal relationships.
