Online Public Access Catalog (OPAC)

An Online Public Access Catalog (OPAC) is a digital database that allows users to search and locate library resources, such as books, journals, DVDs, and other materials, from a library’s collection. Accessible via the internet or library terminals, it provides real-time information about the availability, location, and details of items. OPACs streamline the process of finding materials, making it easier for users to identify what’s in the library, whether an item is checked out or available, and how to access or reserve it. They are essential tools for efficient library management and user navigation.
