We present an approach to operationalizing discovery in literacy research by describing a diagnostic, abductive methodology. This methodology treats products of videotaped interviews and participant-authored footage as narrative data produced in scenes of literacy sponsorship. In describing the operations of our diagnostic approach, we foreground our process of discovery via LiteracyCorps Michigan, our ongoing, long-term research project. We offer this methodology as a research practice that can bring new understandings of how literacy sponsorship operates. (Contains 3 notes.)
