The mentor relationship between teacher and student was once an essential part of academic training. In the latter half of the twentieth century, this type of relationship diminished as large universities placed more emphasis on research, and faculty responded by turning some attention away from their students. This publication seeks to stimulate a renewed interest in bringing mentoring back into academic circles. Sections at this site include: the Ethics of Mentoring; Mentoring for Undergraduates; Graduates; Postdoctoral Students; Junior Faculty, How to Improve the Quality of Your Mentoring; and an extensive bibliography with mentoring and career advice. Sponsored by the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine, this multi-authored publication can be read as a full-text on-line document or ordered through this site.
