Recent historical examinations of nonliterary, nontheoretical texts within their activity settings have aimed to identify the historically developed communicative and rhetorical resources currently available to writers and to reveal the dynamics of the formation, use, and evolution of those resources. These studies, in examining communal literate practices, combine theoretical, empirical, and practical concerns by building theories of the middle range. This methodological article elaborates how theories of the middle range can guide research through identifying interrelated levels of research questions (originating, specifying, and site specific) and identifying strategic research sites. This article further elaborates methods of finding, selecting, and analyzing relevant texts and placing them within appropriate social and historical contexts.
