FIVE LAWS OF LIBRARY SCIENCE 

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. These laws provide a framework for understanding the principles and functions of libraries. They are as follows:

These laws are:

1. Books Are For Use

2. Every Reader His/Her Book

3. Every Book Its Reader

4. Save The Time Of The Reader

5. The Library Is A Growing Organism

1. Books are for use: This law emphasizes that the primary purpose of a library is to make its resources, especially books, available for use by the community it serves. Libraries exist to provide access to knowledge, and materials should not be hoarded or kept away from those who need them.

2. Every reader their book: This law implies that libraries should strive to match the right book or resource with the right reader. It promotes the idea that libraries should cater to the diverse needs and interests of their users, ensuring that everyone finds something relevant and valuable.

3. Every book its reader: This law suggests that every book or resource in a library has a potential reader or user. It underscores the idea that libraries should acquire and maintain a wide range of materials to meet the varying interests and information needs of their patrons.

4. Save the time of the reader: This law underscores the importance of efficiency in library services. It encourages libraries to organize their collections in a manner that saves users' time when searching for information. This can be achieved through effective cataloging, classification systems, and well-organized library spaces.

5. The library is a growing organism: This law recognizes that libraries should evolve and adapt to the changing needs and technological advancements of society. It emphasizes the importance of continuous development and expansion of library collections and services to remain relevant and effective.

                                These laws of Library Science are the "fundamental laws" of Library Science. These are applicable to any problem in the areas of library science, library service, and library practice. These laws are like pot containing oceans. Prior to their enunciation, the subject of Library Science had no philosophy. These laws gave a philosophical base, guaranteeing an everlasting future to the subject of library science, the profession of librarianship, and the use of libraries. These laws have provided a scientific approach to the subject of library science. Even though S.R. Ranganathan proposed the Five Laws of Library Science before the advent of the digital age, they are still valid and equally relevant today. These laws serve as foundational principles for librarians and library professionals to guide their work in building and maintaining libraries that serve the needs of their communities effectively.
