Larry Beck's scholarship has had an immense effect on the field of interpretation. He is the author or co-author of such notable titles as Interpretation of Cultural and Natural Resources, Interpretive Perspectives, and Gifts of Interpretation: Fifteen Guiding Principles for Interpreting Nature and Culture, as well as a now 26-part series in Legacy magazine, called "Justice for All." Recently retired after a 43-year career as a professor at San Diego State University, Larry joins hosts Paul Caputo and Song Stott to talk about the past, present, and future of interpretation.
