Booth Library On-Line Circulation System (BLOC)
Paladugu V. Rao, B. Joseph Szerenyi · Information Technology and Libraries · 1971
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.
