Krishna Subramanyam arranged scientific and technical literature in a circular model in the 1970s. As a pedagogical construct, the circle conceptualizes the processes of producing and consuming information. Although more than twenty years old, the model is still valid. Can it be adapted to help undergraduate students of today's information literacy curriculum understand the structure of the information they need to be able to use to succeed as students and as professionals? This paper presents the model, the revision, and its application to the information literacy curriculum for engineering and technology students.
