Ranganathan's Five Laws of Library Science

Ranganathan's Five Laws of Library Science are foundational principles for libraries. They state: 1. **Books are for use**: Libraries exist to provide access to books and information. 2. **Every reader their book**: Each person should find materials that suit their interests and needs. 3. **Every book its reader**: Every book has a target audience; libraries should help connect readers with the right books. 4. **Save the time of the user**: Libraries should be organized and efficient to help users find information quickly. 5. **The library is a growing organism**: Libraries must evolve and expand to meet changing information needs.
