Though librarians have always recognized the need to educate users in the two broad areas of library skills--location of resources and their use--there is little research on how such instruction can be best done. Theories that do exist seem far different from actual practice. Both practitioners and writers agree on one point: library skills should be taught as they are needed by the student. Whether this functional instruction should be "formal" or "informal" is a matter of debate among librarians. Location skills are invariably stressed by librarians in instructional programs. The main location tools are the card catalog, the library's classification system, and published indexes. Use skills include: understanding the types of resources and the kind of information found in each, interpreting this information, selecting from it for one's own purposes, evaluating materials, and synthesizing ideas from various sources. The teaching of use skills should be recognized as the joint responsibility of teachers and librarians. Both location and use skills are closely connected to the reasoning and study skills elements of The Essential Learning Skills Television Project. (Author)
