Assessing impact is increasingly critical to the survival of services: managers now require comprehensive information about effectiveness, especially in relation to users. Outlining a rigorously tested approach to library evaluation and offering practical tools and highly relevant examples, the new second edition of Evaluating the Impact of Your Library enables library managers to get to grips with the slippery concept of service impact and to address their own impact questions in their planning. Markless and Streatfield fully update the text to include international approaches to qualitative library evaluation, new international research, and current debates on the evolving nature of evaluation, as well as reflections on the importance of involving stakeholders and of evaluation to guide advocacy.
