IIT Mandi has a leisure reading library called Book-Nook, which is a valuable resource for the students and staff of our institution. It was started in September 2010 by Mrs. Priscilla Gonsalves and Dr. Shweta Garg with more than 400 books. The books were of recreational nature and for leisure reading. The subject coverage of books collection is fiction, self-help books on planning and improving one's life, books on Himachal and the Himalayas, and small collections on religion, nature and Indian history, society and politics. The purpose of starting the Book Nook was to promote a culture of reading and learning among the students.

In following years, more books were added to the existing collections and the collection included innovation, entrepreneurship, world history and society, and science. By the end of 2012, the collection has grown to more than 1000 books. Since 2012, Book Nook has continued to grow. It has added collections on parenting and business & management and now have a total of more than 2600 books. Book Nook offers a quiet place to sit and explore books and magazines. Over the years, this library has also organized a variety of events including story time for children, discussions on books and authors, and, most recently, a chance to interact with a successful author.

Currently the Book-Nook is taken care of by Dean Students Office and is run by a team of dedicated volunteers, who manage the issuing, returning, and shelving of the books. The library is located opposite of the Guest House, North Campus in a single hall with limited capacity, which can accommodate up to 20 people at a time. The library has a comfortable and cozy atmosphere, with adequate lighting, ventilation, and seating arrangements.

The library provides many benefits to the users, such as enhancing their knowledge, improving their language skills, developing their critical thinking, and stimulating their imagination. The library also fosters a sense of community and belongingness among the users, who can share their opinions, insights, and experiences with each other. The library also organizes various activities and events to encourage reading and learning, such as book clubs, reading competitions, book fairs, author talks, etc.
