In this extended meditation, Jean Lave interweaves analysis of the process of apprenticeship among the Vai and Gola tailors of Liberia with reflections on the evolution of her research on those tailors in the late 1970s. In so doing, she provides both a detailed account of her apprenticeship in the art of sustained fieldwork and an insightful overview of thirty years of changes in the empirical and theoretical facets of ethnographic practice. Examining the issues she confronted in her own work, Lave shows how the critical questions raised by ethnographic research erode conventional assumptions.
