    Abstract
    Several studies on OPACs have been made since the early 1980s. However, OPAC development has been governed by systems designers, bibliographic networks and technical services librarians, but not necessarily according to user needs. Existing OPACs demonstrate differences, for example, in the range and complexity of their functional features, terminology and help facilities. While many libraries have already established their own OPACs, there is a need to bring together in the form of guidelines or recommendations a corpus of good practice to assist libraries to design or re-design their OPACs.
