This guide consists of a series of behavioral objectives for the student, K-12. It has been prepared by librarians to aid teachers in using the library as an extension of their classroom teaching and to aid librarians in providing the needed materials and activities for both teachers and students. It should be useful to teachers in planning challenging learning situations and experiences. It will, when properly used, serve as a control for the teaching of library skills according to the student's needs and abilities so as to provide each student with a range of skills and pleasures that he may carry on and increase throughout his adult life. The assumptions of the guide are that: (1) instruction in library skills should be triggered by the classroom assignment, (2) library skills should be part of the total curriculum, (3) each reference tool should be taught as part of a larger undertaking, (4) instruction should be continuous and cumulative throughout grades K-12 and (5) some library activities should be planned to introduce enrichment and cultural forms to serve individual and group interests.
