A user-friendly algorithm

Abstract: The interface between a person and a computer can be looked at from either side. Programmers tend to view it from the inside; they consider it their job to defend the machine against errors made by its users. From the outside, the user sees his/her problems as paramount. He/she is often at odds with this complex, inflexible, albeit powerful tool. The needs of both people and machines can be reconciled; users will respond more efficiently and intelligently if they receive meaningful feedback. A “user-friendly” algorithm that covers a wide range of interactive environments and is typical of most operating systems and many application programs is presented.

Library automation in the United States of America

Abstract: The review, which covers the past, present and future of library automation, begins with the establishment of networks, describing the role of OCLC and the adoption of MARC. The second step is seen as the growth of online databases, with particular reference to Lockheed, SDC and BRS. Costs, however, have deterred full use of these. A case is made for standardisation of formats. The effect of online systems on retrieval is related to the increasing interest in document delivery systems. The contribution of mini‐ and microcomputers to this area is noted. Centralised shared systems have allowed automation to progress. All this needs paralleling in the library schools which have difficulty in providing the facilities. The real problem is still that of making systems user friendly. Perhaps librarians need to cultivate self‐sufficiency in programming using easy high‐level languages like FORTH and SPEAK‐EASY. Wordprocessors also will need to be a standard part of library equipment. The future must lie in achieving access to all information from a terminal.
