As a core value of librarianship, sustainability is not an end point but a mindset, a lens through which operational and outreach decisions can be made. And it extends beyond an awareness of the roles that libraries can play in educating and advocating for a sustainable future. As the programs and practices in this resource demonstrate, sustainability can also encompass engaging with communities in discussions about resilience, regeneration, and social justice. Inspiring yet assuredly pragmatic, the many topics explored in this book edited by members of ALA's Sustainability Round Table and ALA's Special Task Force on Sustainability include

• a discussion of why sustainability matters to libraries and their user communities;
• real-life examples of sustainability programming, transformative community partnerships, collective responses for climate resilience, and green building practices;
• lessons learned and recommendations from library workers who have been active in putting sustainability into practice;
• the intersection of sustainability with the work of equity, diversity, and inclusion;
• suggestions regarding the revision of library and information science curriculum in light of the practical need to build community resilience;
• an examination of how libraries' efforts to support Doughnut Economics can bolster the United Nations' work on the Sustainable Development Goals, which seek to address the global impacts of climate change; and
• potential collaborators for future sustainability-related initiatives.
