LIMITATIONS OF WEB-OPAC
Despite the increasing use of OPACs nowadays, there are many
limitations of OPACs. These are listed below.
• Do not make available adequate help in the conversion of
the inquiry terms into the terms used in the catalogue.
• Do not make available online vocabulary aids helpful for
subject focusing/identifying vocabulary that broader or narrower than the idea
of search.
• Do not automatically help the user by providing substitute
formulation of the fails.
• Do not guide the search from successful free wording search
terms (e.g. title words) to the related subject headings or call numbers assigned
to a broader range or linked resources.
• Do not give adequate information in the retrieved
bibliographic records (e.g. table of contents, abstracts and book reviews) to
allow the user to judge the utility of the documents.
• Do not rating the retrieval sets in decreasing order of
probable relevance to the user‘s search criteria.
• Does not present open-ended, explanatory browsing during
pre-established linkages between records in the database to retrieve resources
linked to those already found?
