LIMITATIONS OF WEB-OPAC

 


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?
