An online public access catalogue, commonly referred to as OPAC, is a digital system that allows users to access and search for information on books, periodicals, multimedia resources, and other materials available in a library or information center. It serves as a comprehensive database that provides users with a virtual platform to explore available resources from the comfort of their own devices, eliminating the need for physical access to the library's collection.
The primary purpose of an OPAC is to offer users a user-friendly interface to search, locate, and assess the availability of materials in the library. It allows users to search using various search parameters, such as title, author, subject, keyword, or publication date. The catalog provides detailed information about each item, including its location, availability status, and sometimes additional descriptions or summaries.
Furthermore, an OPAC often offers advanced functionalities, including the ability to reserve or request items, renew loans, access digital content, and view borrowing history. Some OPAC systems also support additional features like recommendations based on users' search history or personalized reading lists.
OPACs have greatly enhanced the accessibility and efficiency of libraries and other information centers by providing an intuitive, user-friendly, and convenient system to browse and retrieve information. They have revolutionized the way people interact with libraries, helping users save time and effort by allowing them to access valuable resources remotely and facilitating efficient resource management for librarians.
