An Experimental On‐line Retrieval System using Ultrafiche

Abstract

The command language devised for an experimental on‐line information retrieval system which uses an automatic Ultrafiche terminal to store and display the textual data is described. A conversational reference retrieval system was set up on a PDP‐8 minicomputer with a data base selected from Computer & control abstracts. Search facilities available include Boolean logic, left‐hand and right‐hand truncation, universal character, and a profile editor.
