This article describes protocological rhetoric as a conceptual tool for exploring and changing institutions. Protocological rhetoric is an extension of two lines of thought: Porter, Sullivan, Blythe, Grabill, and Miles's institutional critique and Science & Technology Studies's (STS) concept of information infrastructure. As a result, protocological rhetoric imagines institutions as networked information infrastructures. This article describes the method and provides an example through historical case study. I suggest that the approach provides methods for actively transforming institutions.
