Book excerpt: The need for public libraries to tackle social exclusion and engage in social justice becomes ever more urgent as the gap between rich and poor continues to widen, and the very survival of public libraries in the heart of the community is open to debate. If public libraries are to develop and grow in the future and become relevant to the majority of their local communities, then they need to abandon outmoded concepts of 'excellence' and fully grasp the 'equity' agenda. This book examines the historical background to social exclusion and the strategic context in terms of government and professional policy. The authors propose a compelling manifesto for change and outline practical ways in which public libraries can be transformed into needs-based services.
