Information technology changed library environments and gave the process of information retrieval many more avenues, no longer making main entry an author or title record. Computer catalogues have made main entries obsolete, altered how they make entries and transformed catalogues into search stations that can use various prompts to retrieve information. Computer cataloguing, no longer limits libraries to only author and title entries, and they are necessarily connected to circulation records. They are more flexible, allowing more entry points and quick changes in the system, but they are quite expensive.
The present book describes the role of information technology in library cataloguing. It is meant for students who have opted library science as their subject of graduation. It is also useful for those librarians who do not receive formal and regular training in library science.
