Data concerning librarians' beliefs about possible problems associated with dual career marriages, as well as data on the educational and marital histories of librarians, were collected by a mail questionnaire distributed to a random sample of alumnae from the graduating master's classes of the School of Library and Information Studies of Texas Woman's University from 1961 to 1985. The "typical librarian," according to the data, married young and stayed married, has two children, received her professional education in her late 30s, works full-time, and finds that the only conflict between marriage and her professional and career development is the geographical limitation imposed by her spouse's job. There are no significant differences between the attitudes of single and married librarians concerning the impact of marriage on careers. (Author/KM)
