The Master Technical Plan is divided into the following four main parts: (1) "Indroduction." (2) "A Description of the Proposed National Medical Retardation Information and Resource Center (NMRIRC)," consists of a series of descriptions of how the national center will serve its various organizational and individual constituents. This section explains the technical rationale that led to the construction of the technical plan for the National Medical Retardation Information and Resource Center (NMRIRC); (3) "Master Technical Plan for the NMRIRC." This is intended to be the durable vehicle of design for the eventual national center and also the master planning document for the President's Committee. Once reviewed, corrected, and approved by the President's Committee or the delegated representatives of the Secretary the plan should be the blueprint for the national center; and (4) "Proposed EDUCOM Support of the NMRIRC," includes some historical information on the Interuniversity Communications Council (EDUCOM), a roster of institutional members, a proposed staffing plan, and an estimate of costs for EDUCOM participation.
