This guide presents a series of articles which give pointers, hints, and examples of day-to-day development activities school librarians can use to hone their professionalism. The first of five sections describes ways in which librarians can provide professional service and lists some markers of professionalism. The second section presents one librarian's personal observations from her continuing education courses, and a list of library challenges is given.
