Book excerpt: Are librarians and libraries relevant in the 21st century? This is a fundamental question and one that presents differing opinions across the many diverse information sectors. If there is a continuing need for libraries and for librarians, then how do library leaders obtain strategic support when there appears to be a lack of clarity or understanding about the very purpose of libraries at a time when economically, libraries are under pressure to develop new business models and be more commercially focussed? Bold Minds: Library leadership in a time of disruption brings together international leaders who frame many aspects of the current library provision and who carry responsibility for the library models of the future to consider how librarians and libraries can be a driving force in a time of disruptive economic, technological and cultural change. Each chapter critically presents a short leadership provocation regarding libraries and their purpose, encompassing impact, service delivery, collections, staff skills and professional training and assessing what it means for leaders, their sectors and organisations, and how they have developed their personal leadership signature. This book will be invaluable to library and information professionals in a range of public and private sector libraries as well as policy makers in services where libraries are a component. It will also be useful for students, educational establishments, and IT professionals with an information management element to their work.
