Presenting this cost analysis as a supplemental volume, separate from the main report, allows the chief activities in implementing the Processing Center Design to be correlated with costs as of a particular date and according to varying rates of production. In considering the total budget, three main areas are distinguished: (1) Systems Development, (2) Conversion and Maintenance, and (3) Output Services. Separate costs are stated for the different operational phases of Monographs and Serials, although both types of data are considered as sharing management and development costs. The analysis first covers the purpose, scope, allocation and descriptive basis of the three main areas for a six-month preparatory period to establish the Center and three years full production. Appendices include a reprint of the preliminary organizational design (with minor revisions) and supporting details for the three main areas. Volumes I-IV of this report are available as ED number 036 305 to 036 308. (Author/NH)
