Abstract
The purpose of this paper is to further develop the general program of managing overflows by attending to the managing of leaks. Specifically, the paper explores efforts to manage the problem of shoplifting in US grocery retailing during the period 1922–1969. The study identifies three different yet interrelated ways of managing leaks: identifying, preventing, and caulking leaks. Each of these rests on a combination of skills and devices as well as on efforts to align with the other ways of managing leaks and routinize them as part of ordinary retail operations. By providing an analysis of leaks management the paper proposes a theoretical and empirical complement to the research program on managing overflows, which has previously primarily focused on overflows in the sense of excess, surplus and abundance.
