This document is a tool that is intended to assist school-based educator partners in understanding their own roles and the dimensions for growth that enable implementation of the program "Partners in Action: the Library Resource Center in the School Curriculum." The program involves the integration of information skills, literature, media, and information technology in the Brant County (Ontario) public schools. This handbook is for principals and vice-principals to help them move from print-oriented, library-based lessons planned only by the teacher-librarian to plans for learning through experience which are resource-based, curriculum integrated, and cooperatively planned lessons. It is the principal's role to facilitate the implementation of cooperative planning among librarians, teachers, and other professionals. Guidelines are given for selecting a teacher-librarian and defining the position, as well as for management under the Partners in Action approach. Appendixes include: (1) the Growth Profile, an implementation tool; (2) the Growth Profile User's Manual; (3) possible interview questions for selecting the teacher-librarian; and (4) some additional resources for program implementation, with suggestions for the program process, transitional periods, time management, and library collection development.
