The OPAC (Online Public Access Catalog) at the UNISA Library is an online cataloguing system that allows users to search for and access the library's collection of materials, including books, journals, articles, theses, dissertations, conference proceedings, reports, and other resources in various formats such as print, digital, audio, and film. It provides information about the availability, location, and status of these materials and enables users to request or reserve items for borrowing

. Users can access the UNISA Library OPAC through the library’s website or via a mobile app available on Google Play and the App Store. The OPAC also serves as a gateway to remote electronic resources, including electronic journals, online databases, digital images, and other scholarly internet resources selected for their relevance to teaching and research at UNISA. This integration means the OPAC is not only an inventory of physical holdings but also a means to access selected electronic and internet-based resources

. To use the OPAC and access electronic resources off-campus, users need to register a myUnisa password. The system supports searching by various criteria and provides links to electronic resources where available. The library also offers tools like the e-Journal Finder to identify full-text journal availability in subscribed databases
