"Diverse and distinct analytic traditions, theories, and methods exist across the field of Indigenous literary studies—corollary to the diverse and distinct Peoples existing across the vast territories of the United States and Canada. As a starting place, this overview of the field offers a synthesis of four key principles drawn from Indigenous literary scholarship and practice. Each of these four principles conveys key concepts in this field of study: (a) that Indigenous literary studies is centered in Indigeneity, (b) that critical work in Indigenous literary studies requires relational ways of being, (c) that Indigenous literary studies requires critics to engage beyond the text, and, (d) that engaging in Indigenous literary studies means engaging with Indigenous storyways, or ways of knowing, being, and doing with and through story."
