Every library needs to understand its patrons and potential users, yet the prospect of formal research can be so daunting that many libraries don't carry out information needs assessments unless they can afford a consultant. Here in one handbook are the essential theories, tools, and techniques library managers need to create a structured, planned, and well-executed assessment of user needs. Westbrook balances sound theory with practical applications for each phase: planning, research methods, data gathering, analysis, and action. The workbook template on the companion disk allows you to create a customized plan incorporating the input of staff, trustees, friends, directors, and volunteers. Includes examples of successful recent studies from public, school, and academic libraries.
