Rapid developments in information technology and media have resulted in increasingly diverse strategies for information retrieval by readers and users. The duty to cope with this phenomenon and to master the situation forms one of the biggest challenges facing libraries. In order to strengthen the awareness of the potential of tools for management and strategic planning, a two-day meeting was held under the auspices of IFLA's Management & Marketing Section in Bergen, Norway in August 2005. Managers of different types of libraries, researchers and educators from five continents shared their experiences with research methods, data collection, evaluation, performance measurement, best practice strategies and policies. This book contains their presentations in the form of full length articles.
