S.R. Ranganathan and His 5 Laws of Library Science: A Comprehensive Study

Abstract

Dr. Shiyali Ramamrita Ranganathan (1892–1972) is known as the “Father of Library
Science in India.” He was a visionary who transformed librarianship from a custodial
profession into a dynamic, user-centered field. Ranganathan began his career as a
mathematician before transitioning into librarianship. He developed the Five Laws of
Library Science in 1928 and published them in his influential book in 1931
(Ranganathans1931). These laws provided libraries with both a philosophical and practical
foundation for their functioning. They continue to influence libraries around the world,
including in the digital era (Ramesh Babu, 2011). This study examines Ranganathan’s life, the
historical background and meaning of the Five Laws, and their evolution and continued
relevance in modern Library and Information Science (LIS). It explores how these laws
remain important guiding principles despite rapid technological advancements and changing
information environments. The 5 Laws of Library Science is a theory proposed by S.R.
Ranganathan in 1931, detailing the principles of operating a library system. Five laws of
library science are called the set of norms, percepts, and guides to good practice in
librarianship. Many librarians worldwide accept them as the foundations of their philosophy.
Dr. S.R. Ranganathan conceived the Five Laws of Library Science in 1924. The statements
embodying these laws were formulated in 1928. These laws were first published in
Ranganathan's classic book entitled Five Laws of Library Science in 1931.
