The scope of Phase II is the design of a system for document control within the National Agricultural Library (NAL) that will facilitate the processing of the documents selected, ordered, or received; that will avoid backlogs; and that will provide rapid document location reports. The results are set forth as follows: Chapter I, Introduction, establishes a frame of reference for the results of the design study and enumerates the objectives of the future system. Chapter II system Profile, describes the functions of the automated system operations in the order of their operational sequence. Chapter III, Design Background, specifies the broad system requirements and constraints, including design trade-off considerations. Chapter IV, System Design, encompasses the automation of five major functions accomplished in the present manual system and an additional Data Review function, and describes the computer files that contain complete bibliographic information. Chapter V, Implementation, recommends the use of a systems engineering contractor and describes the orientation, training, personnel requirements, and organization for the data-processing group.
