The Online Public Access Catalogue (OPAC) of the Library allows users to explore all bibliographic records within the Central Library database using the web-based search interface powered by Koha Library Management Software. Users can search the OPAC by author, title, subject, call number, and ISBN. Additionally, OPAC provides users with information about their checkout status, issue history, and the ability to reserve books online, along with access to more advanced services. The system also updates users on new arrivals in the Library. Users can conveniently check the availability of library books through the Web OPAC available at http://library.iiserbpr.ac.in.
