Third Law of Library Science: Every Book Its Reader

The statement "Every book to its reader" is a core principle in library science. This statement directly corresponds to the Third Law of Library Science, as formulated by the renowned Indian librarian and mathematician Dr. S.R. Ranganathan.

Dr. Ranganathan's five laws of library science provide a foundational framework for library management and services. Let's examine them briefly to understand why the given statement fits the third law:

• First Law: Books are for use. This law emphasizes that books should be made accessible and utilized by patrons, rather than being kept idle.
• Second Law: Every reader his/her book. This law focuses on the reader's perspective, asserting that every individual seeking a book should be able to find and obtain the specific book they need.
• Third Law: Every book its reader. This law shifts the focus to the book itself, stating that every book available in the library collection should have a corresponding reader or user who will benefit from it. It implies that the collection should be organized and promoted in a way that ensures each book finds its intended audience.
• Fourth Law: Save the time of the reader. This law highlights the importance of efficiency in library services. Library systems, cataloging, and staff assistance should be designed to help readers find information quickly and easily.
• Fifth Law: Library is a growing organism. This law recognizes that libraries are dynamic entities that need to evolve over time, continuously expanding their collections, services, and infrastructure to meet changing user needs and knowledge advancements.

Therefore, the statement "Every book to its reader" is the precise articulation of the Third Law of Library Science, emphasizing the need to connect each item in the collection with its potential user.
