This report presents documentation of files, of file organization, and of 42 of the modular program subroutines used in a pilot project devised by the Oregon State University (OSU) Computer Center to simulate procedures in the Acquisitions Department of the OSU Library. A total of 224 bibliographically verified requests for monographs, 30 vender names and addresses, and 62 campus departments having library fund allocations comprise the three files constituting the main data base for the pilot project. Fixed field formats are used for bibliographic input; the vendor file uses a variable field input. Searching is on both fixed and variable lengths and the initial methods of accessing elements in the files are through table lookup, sequential match, and algorithmic search and retrieval strategies. The modes of interaction among the computer configuration, the programming system and the user in the project are on-line, real-time, time-sharing, and conversational. Documentation of programs in this report assumes the use of a cathode ray tube terminal as the input/output device; however, these same programs have since been modified for use on the teletypewriter. An area of programming not included is the algorithmic search used for locating the main entry. This report documents work done from May 1967 through January, 1968. (Author/CM)
