ABSTRACT
What is the most critical ability that a new librarian should cultivate in preparation for a reference career? Some would claim communication skills are vital; some would advise concentration on extensive knowledge of reference sources; others might state a case for computer literacy skills. This article argues that the single most important skill for a reference librarian to possess is the ability to think critically about the use of reference materials. Illustrations are given to demonstrate the primacy of this proficiency in all areas of reference responsibility and suggestions are made concerning the need for increased focus on critical thinking in education and training programs.
