Fourth Law of Library Science by Ranganathan

Dr. S. R. Ranganathan, a pioneering figure in library science, introduced five fundamental laws that guide the organization and functioning of libraries. These laws are widely respected and followed in the library community worldwide.

Dr. Ranganathan's Five Laws of Library Science

It is essential to know the sequence of these laws as formulated by Dr. Ranganathan:

First Law:

Books are for use.

Second Law:

Every reader his/her book.

Third Law:

A book is for every reader.

Fourth Law:

Save the time of the reader.

Fifth Law:

The library is a growing organism.

Explanation of the Fourth Law

The question specifically asks to identify the fourth law from the options provided. According to the standard enumeration of Dr. Ranganathan's laws:

• The first three laws focus on the availability and accessibility of books for readers.
• The fourth law, "Save the time of the reader," emphasizes the need for efficiency in library operations. This means ensuring that library resources, staff, and systems are arranged to help users find what they need with minimal delay. Techniques like proper classification, cataloging, and user-friendly layouts are key to fulfilling this law.
• The fifth law addresses the need for libraries to adapt and grow over time, much like a living organism.

Based on this established order, the option "Save the time of the Reader" correctly represents the fourth law of Library Science as defined by Dr. S. R. Ranganathan.
