Abstract:
A very enormous role has been vested to libraries, information centers due to information growth and explosion. Given this opportunity, it is much important in controlling, organizing and dissemination of information and this has lead for establishing speedy bibliographic control strategies and methods. With the rapid use and development of computer cataloguing than the traditional cataloguing together with its application of modern ICT has diverted to online catalogue both in-house and web based forms. Even though, the author, title and subject are used as access points, different areas pertaining to the subject available in document cannot be accessed through that mean and therefore different areas in subject domain will have be accessed through different subject headings. This can be done with the provision of subject headings to the relevant catalogue. When providing subject headings proper authority control have to be followed. There is a dire need for the authority control of subject headings. To investigate whether authority control mechanism is used by the national library is the problem of this study.
