Is your Web OPAC the best it can be?

Web OPAC or Web-based Online Public Access Catalog of Library Management Systems is widely used in both public and academic libraries for quick and easy access of the library resources- both conventional and digital. It is perfect to say that the foundation of the modern, digital library has been laid by the Web OPAC and libraries owe a lot to it. It worked as a catalyst for change and paved the way for new and improved services, such as online catalogs, digital collections, e-books, etc, that can be accessed anytime, anywhere.


Libraries that were using OPAC and now switching to an advanced alternative- Web OPAC. Most likely your library has also adopted Web OPAC as it has become a hope for the libraries to sail through these unprecedented pandemic times and a better future. 

What to expect from the Web OPAC switch?

An OPAC can be accessed in the library, institution campus over LAN/Intranet, whereas the Web OPAC can be accessed anytime, anywhere in the world through the internet. Also, Users need to follow the program of the particular OPAC software used in the library while  Web OPAC has HTML files that hyperlink to the subject disciplines or areas.
