"For years, the dynamic duo of Denis and Pontille have been producing some of the best work on maintenance and repair out there – full stop. This new translation is a landmark contribution, and one we’ll be reading and learning from for years to come."Steven J. Jackson, Professor of Information Science and Science and Technology Studies, Cornell University"This is a spirited book that, with its large array of cases, will gradually get you sensitised to the fragility of a great diversity of things, so that you come to admire the hands-on experts who nurture stuff and tools, rather than tolerating their decay."Annemarie Mol, author of The Logic of Care and Eating in Theory"This book makes the thinking around maintenance into a timely intervention, creating a distinctive proposition that will appeal to a broad readership. The writing is beautiful and accessible, without losing in theoretical sophistication. The thinking is philosophical and ethnographically rich at the same time, and the book combines and deploys a remarkable depth of scholarship, careful attention to empirical detail and stories, as well as a generous approach to theorising."María Puig della Bellacasa, author of Matters of Care
