The 21st century has seen a transformational shift in the design of college and research libraries, one focused more on user experience and engagement than on collections. Dramatic changes in library design have been driven by changes in the core functions of universities and colleges: the reliance on digital tools and content, integration of technologies into pedagogy and research, and emphasis on the active and social aspects of learning, inclusion, and community engagement. Planning for these vibrant spaces needs to incorporate new program and staffing strategies, robust technical infrastructure, human-centered design, and flexibility to enable ongoing change. Designing Libraries for the 21st Century explores these trends and identifies promising strategies for new or renovated library space. The book features an impressive array of authors drawn largely from the conference of the same name, providing guidance, principles, and a wealth of creative ideas for spaces, technology, programs, and partnerships. Twenty-nine chapters packed with full color images and illustrations explore these themes: 21st-Century Academic Libraries in an Evolving Environment Aligning with the Institutional Vision Working with Architects, Designers, and Planners Key Issues in Planning Collaborations and Convergence Leadership, Organizational Change, and New Staff Roles Programming for Research, Learning, and Community Looking Ahead  Often major building projects focus primarily on the physical facility, but this volume makes the case for designing libraries in a much more holistic fashion. Today all types of libraries are engaged in reimagining their roles and the spatial design through which this new vision will be realized. Both inspirational and practical, Designing Libraries for the 21st Century is a must read for librarians, architects, planners, academic leaders, and anyone interested in the future of libraries.
