A recursive presentation of a communication format is discussed and a form of pertinent notation proposed. Recursive notation permits presentation of an interchange format in more general terms than heretofore published, and expands application possibilities.
An industry inventory technique adapted to a university library's computer based circulation system as one aid in identifying heavily used books for multiple-copy purchase.
An entry/title compression code is proposed which will fulfill the following requirements at the Library, University of Saskatchewan: 1) entry/title access to MARC tapes; 2) entry/title access to the acquisitions and cataloging in-process file; and 3) entry/title duplicate order edit within the acquisitions and cataloging in-process file. The study which produced the code and applications for the code are discussed.
An on-line circulation system developed at a relatively small university library demonstrates that academic libraries with limited funds can develop automated systems utilizing parent institution's computer facilities in a time-sharing mode. In operation since September 1968, using an IBM 360/50 computer and associated peripheral equipment, it provides control over all stack books.
