A Manual Information Retrieval System

A manual information retrieval system which is applicable to a library or bibliography of a few thousands of documents is described. It was designed for an engineering research program and has been used successfully on several relatively small research programs in the past few years. The system uses a Royal-McBee Keysort (KS-3718) card as the medium of information storage. The coding system is described in detail. The ``keyword'' concept is discussed and an example is given.
