This document discusses integrating information literacy threshold concepts into course design through collaboration between instructors and librarians. It provides an example of how an English instructor and librarian collaborated at Virginia Tech to incorporate threshold concepts like "research solves problems" into an English 1106 course. The librarian introduced concepts in an initial session and reinforced them in a second session focused on a major research project, helping students cross an important threshold for research skills. The goal was to give students a deeper understanding of quality sources and help them produce stronger research projects.
