Book banks are separate sections in libraries where textbooks, reference books, and other miscellaneous books can be reserved for special categories of users, such as economically backward students. The main objective of book bank formation is to provide informational and educational assistance to meritorious students who may not be economically rich. The following are some of the well-defined objectives of book banks:

• To encourage meritorious students by providing informational and educational assistance from the institute itself.
• To support scheduled caste and scheduled tribe students who cannot afford expensive education.
• To distribute books to students related to their studies and career at a subsidized rate.
• To establish book banks for students from marginalized communities who cannot afford to buy books.
• To improve literacy.
• To provide efficient services to library users.
• To conduct book exhibitions, seminars, workshops, quiz programs, and career guidance to encourage students, teachers, and other users to use library resources and facilities.

Book banks are an important resource for students who cannot afford to buy books and need access to educational materials. They help to promote literacy and provide educational assistance to economically backward students.
