"It is not a passive role that the librarian plays, content to be a passer-out of books, a checker-up of overdues, or just a looker-on in the classroom. She makes an active and positive contribution to the instructional program of the College. She recognizes as one of her most important obligations the training of students themselves to use the library efficiently. She is essentially a teacher as she helps a student define her problem, weigh various approaches to its solution, and finally select and locate helpful materials for study. The librarian is teaching effectively when she helps a reader identify and point up her interests and select materials to satisfy, deepen, and expand such interests. What is more, she has the important opportunity for teaching at the particular time the student is most actively feeling the need for help — a real psychological advantage."
