Genre has long been used by Writing Studies ethnographers as a theoretical orientation and analytical tool to bridge text and context. This article describes how genre-based ethnographies as "methodology" might get taken up at the level of "method." Drawing on a genre-based ethnographic study as an example and guide, this article presents a process of data collection that builds ethnographic sites "from" genre by emergently identifying chains of data sources and collection techniques emanating from starting genres. Applying a genre orientation at the level of method centers inquiry on writing and mitigates the need to define site boundaries. By articulating how a genre orientation might shape ethnography at the level of method, this article encourages a stronger articulation between research methodologies and methods across the field of Writing Studies. Further, this article can be used as a guide for researchers conducting genre-based ethnographies.
