Online catalogues can be looked at from several perspectives. The design of an online catalogue must take into account a quite different set of circumstances. Considerable diversity exists among users in their level of knowledge about library catalogues and in the extent to which they are familiar with the use of computerized systems. The library will usually have little opportunity to balance its diversity through a planned program of controlled instruction and monitoring. Most people will not use the OPAC as part of everyday routine, and hence their knowledge and skills will not be constantly reinforced.
