This manual is a product of the Media and Mainstreaming Project and a fuller version of the manual included in the interim report "Educational Media for Handicapped Students in Regular K-12 Schools"). It focuses on the media-related needs of handicapped students being mainstreamed into regular K-12 school programs. The emphasis is on how the school library media specialist can use, adapt, or supplement the components of the media center to meet those needs. These components encompass a media program of services and instruction which make the facility, equipment, and collection accessible to the entire school community through the design and management of a professional media staff. To this end an operational model, guidelines, and assessment guide have been developed for use by media personnel in meeting the mandates of P.L. 94-142 (The Education for All Handicapped Children Act). This model consists of the operational model, the guidelines, an assessment guide, and instructions for developing a plan of action using data gathered with the assessment guide. The manual is for use by school library media personnel in meeting the needs of mainstreamed handicapped students. An extensive list of resources is also provided. (GL)
