DrLibSc's Short Notes on "THE FIVE LAWS OF LIBRARY SCIENCE"

 


THE FIVE LAWS OF LIBRARY SCIENCE

Enunciated in 1928 by the late Dr. S. R. Ranganathan, Librarian of the University of Madras, these principles form the philosophical and operational foundation of modern library science. Originally, The Five Laws of Library Science were conceived in 1924 and officially formulated by Dr. S. R. Ranganathan in 1928. They were subsequently published in his classic book in 1931.Every structural development in the discipline can be directly traced back to these five mandates:
