Information technology (IT) has radically improved many aspects of organisational activities.
Computer-based information systems (CBIS) are constantly developed more effective and efficient.
Development of a new CBIS is justified by higher quality of work, more efficient work processes,
and more flexible work practices. However, introduction of the new IS can produce a variety of
problems.
This paper describes the problems observed in the use of a library CBIS in a Finnish scientific
library. The results of the study illustrate well the environment which should be understood by the
designers of computer-based information systems. One important prerequisite of good (re)design
is a wide understanding of the problems that may prevent effective use of a CBIS. In this study we
introduce a classification based on the problems which were found in the case. The classification
describes the causes and effects of the observed problems.
