Librarians, especially those with supervisory and management responsibilities, are leaders within their libraries. The skills used to run the library transfer well within the larger organization. Two librarians who have assumed significant leadership roles within their organizations—a large law firm and a major university—present case studies of their expanded responsibilities and how their training as librarians created and supported these new opportunities. They will demonstrate their decision-making processes that led to their accepting the new responsibilities, and critique the outcomes of their decisions.
