Within the school library profession there is an emerging focus on dispositions, defined as a tendency to exhibit frequently, consciously, and voluntarily a pattern of behavior that is directed to a broad goal (Katz, 1993). Directed focus groups of practicing school librarians were asked to articulate their vision for school libraries of the future. Data from these groups informed development of six dispositional continua to guide both school library education and school librarianship in the 21st century. This study clarifies the dispositions needed by school librarians in the future
