Mentoring in the fields of academia, business, and government has been studied since the early 1970s. The field of library science has recently begun to study this activity among the members of its profession. More research is needed to determine the extent of influence this area of career development has had on the careers of librarians. This study was undertaken to gain the mentoring histories of a representative sample of 100 Ohio public library directors to determine if their gender had any relationship to the gender of their mentor(s). Seventy-six members of the sample responded to a questionnaire, and the data from these responses showed Ohio public library directors to be similar to other professionals in one study but different from those in another study. Women directors were found to give more mentoring to other women, but men were found to be more likely mentored in this study compared to women in another library science study. The survey questionnaire is included in the appendices. (Contains 34 references.) (Author/JLB)
