Online Public Access Catalog
An Online Public Access Catalog (OPAC) is a digital system that allows users to search for and locate library materials, such as books, journals, and multimedia resources. It provides a user-friendly interface where patrons can enter keywords, titles, or authors to find specific items in the library's collection. OPACs are accessible from computers and mobile devices, making it easy for users to browse and check availability.
Most OPACs are part of a larger library management system, which helps librarians manage inventory and track circulation. They often include features like user accounts, allowing patrons to reserve items or renew loans. Many OPACs also provide links to related resources, such as e-books and databases, enhancing the research experience.
