One of my friends is pursuing a BTech from IIT Mandi so I think I’m better positioned to tell you about its library.
IIT Mandi has library facilities on both North and South campuses. The library offers a vast collection of books related to all fields (43,694 books), journeys, and electronic resources (48,746 e-resources). The library also has multiple reading rooms that provide an excellent environment for education. IIT Mandi’s library operations are automated using KOHA software. Additionally, School of School of Physical Sciences at IIT Mandi also has a central library with similar features, including a good collection of AV materials such as CDs and DVDs.
