Answer:
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 are:
First Law: Books Are For Use
Second Law: Every Reader His/Her Book
Third Law: Every Book Its Reader
Fourth Law: Save The Time Of The Reader
Fifth Law: The Library Is A Growing Organism
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.¹
