This article provides an overview of recent work on norms of inquiry. After some preliminaries about inquiry in §1, I discuss in §2 the ignorance norm for inquiry, presenting arguments for and against, as well as some alternatives. In §3, I consider its relation to the aim of inquiry. In §4, I discuss positive norms on inquiry: norms that require having rather than lacking certain states. Finally, in §5, I look at questions about the place of norms of inquiry within normative epistemology.
