A public library is an establishment where books, magazines, and other reading materials are kept for the use of the people at large. Readers and members can read the materials of their choice in a public library. They can also take books to their homes in accordance with the library rules. The utility of a public library cannot be adequately described. It immensely helps in the spread of knowledge. An individual reader cannot buy or procure all the books and journals he wants to read. The students, teachers, and researchers cannot collect all kinds of materials they need to study. Besides, they find it difficult, even impossible to gather books which are out of print or of foreign origin. Public libraries are the reading houses which, in such circumstances, they can fall back upon. Moreover, a public library can develop the reading habit of the people in general. A public library is, therefore, a very important institution.
