The Acquisitions System is just one segment of an overall system design that was made for the entire Technical Services System of the Washington State University Library. After an overall study of the Technical Services System was conducted, a detailed study was made of work in the Acquisitions Department, and the Telecommunications Control Program was designed and developed for the on-line system. The Acquisitions System uses the IBM 1050 typewriter terminal with paper tape reader and paper tape punch. Topics discussed in this report include: the overall design of the Technical Services System, Acquisitions System design, the Library Executive System, direct access file definition, printouts, the acquisitions programs, purchas e request entry preparation, purchase request entry and editing, purchase order writing and handling, book receiving, invoice handling, the standing Order on Approval Program (SOAP) entry, receiving report preparation, initial testing, and plans for incorporating additional activities into the Acquisitions System. Appendixes include information on the Teleprocessing Executive Program, Library Executive System Commands, the Acquisitions System purchase order input procedures, and WISBUM, an assembly language subprogram written to provide a basic input-output for IBM 1050 terminal users.
