In this article, we draw clear distinctions between generic reading comprehension and disciplinary literacy in history. We argue that disciplinary reading restores agency to the reader, changing the typical relationship between text and reader, in which knowledge flows down from one to the other. Sourcing, for example, enjoins readers to engage authors, querying them about their credentials, their interest in the story they are telling, their position vis-à-vis the event they narrate. Contextualization prompts the reader to question the social and political circumstances surrounding the text. In a digital age characterized by unfettered access to information, such skills become essential tools for an informed citizenry.
