Title

Fisheye views as an aid to subject access in online catalogues

Abstract

There are many problems with subject access in online catalogues. One of the major problems is information overload. One kind of this occurs when the display consists of a lengthy segment of the subject index in which a single subject heading is followed by a bewildering array of subdivisons, qualifications and phrases. This problem can be alleviated by presenting the subject index in a summary form that the user can expand to provide more detail as appropriate. Such an approach could be realized within the context of a direct manipulation style of user interface. In particular, a manner of displaying information called 'fisheye views' could be applied to the subject index display
