"What do I do now?" "How do I handle this situation?" or "What do I do for that student?" How many times have you or someone you know asked those questions? In some cases, it may be every day, or in others, occasionally. This new series of case studies describes problems that can be used by educational media students or in professional development workshops. The case situations fall outside the subject matter of traditional library media curriculums and include topics on the "nitty gritty" issues (emergencies, etc.) and on bigger issues such as planning, policies, and personnel. Incorporated within the cases are the concepts on information literacy found in the Information Power: Building Partnerships for Learning guide issued by the American Association of School Librarians in 1998. In a departure from the first two books of case studies in this series, the cases are arranged by topic, rather than by school level. The bibliography will serve as a listing for a basic professional collection that leads to answers to the expected, as well as the unexpected, situations that arise in the functioning of the modern school library media center.
