A talk delivered by Paul Cavanagh and James Kay at the Anybook Oxford Libraries Conference 2015 - Adapting for the Future: Developing Our Professions and Services, 21st July 2015. Universities face the challenge of providing high quality services which meet the demands of users to provide access to more varied resources in a rapidly changing technological environment. This is balanced against the increasing costs of resources and a political and sector-wide institutional need to manage and better account for library budgets. This talk will focus on how the University of Derby is using statistical and decision-based tools to manage and plan library resources effectively; collaborating with publishers, academics, colleagues within the Library and across the library and information sector to develop continuing best practice through evidence-based decision making.
