Mentoring can be a key to success in any field, but it is especially important to early career librarians who are navigating the promotion and tenure process. At our academic library, a mentoring program had been in existence for over a decade, but the process was mostly ad hoc, and there was very little guidance or oversight. Seeing the need for an updated approach, we formed a task force of librarians from different units to revise and update our program. This poster session will describe our process for defining, structuring and implementing a new mentoring program that we hope will meet the needs of our newest colleagues, both tenure track and nontenure track.
