In order to further the argument for the consideration of advising as a high-impact practice, there is a need for the organization of knowledge surrounding advising. This chapter contributes to the ongoing efforts to chronicle the landscape of literature on the scholarship, administration, and practice of advising. Summarization of the major themes found in empirical and best practices literature, as well as a synthesis of learning from advising-related reports is provided alongside the introduction of a typology that draws from Bronfenbrenner's Ecological Model in an effort to organize research approaches to advising in the field of higher education.
