Using data from a learning module embedded in all first-year seminars, researchers found evidence suggesting that librarians are uniquely qualified to deliver information literacy instruction compared to campus faculty. The study analyzes writing assignments from first-year modules taught by either librarians or campus faculty for two academic years. The data indicate that students met the learning objectives more often in modules taught by librarians. The outcome demonstrates the centrality of the librarian's role in information literacy instruction and student learning and helps substantiate the value of academic libraries.
