To meet the academic and research needs of postgraduate students and faculty, the Dewang Mehta Library was established on 30 August 2003 as a dedicated postgraduate library facility. Located in a spacious hall within the Maffei Block of St Aloysius Deemed to be University, the library provides an enriching environment for advanced study and scholarly pursuits.

The library houses a valuable collection of more than 25,000 books and subscribes to over 50 journals, catering to diverse academic disciplines and research interests. It is fully automated with an Open Access system and operates using the Koha Library Management Software integrated with RFID technology. This advanced system ensures seamless circulation services, accurate inventory management, enhanced security, and convenient access through the Online Public Access Catalogue (OPAC).
