This discussion of the mentor/protege relationship in the library setting begins by examining the benefits of mentoring for both individuals and the organization. Characteristics of mentors, guidelines for self-assessment of strengths and weaknesses for a potential mentor, and protege characteristics that will attract a mentor are outlined. Communication skills essential to mentoring are then described, including active listening, giving and receiving feedback, counseling, coaching, and managing conflict and disagreement. Conditions within the organization that encourage or discourage the development of mentor relationships are summarized, and the paper concludes with a discussion of ways that librarians can promote leadership through mentoring.
