The Five laws of library science is a theory proposed by S. R. Ranganathan in 1931, detailing the principles of operating a library system. Many librarians worldwide accept them as the foundations of their philosophy.
These laws are:
- Books are for use.
- Every reader his [or her] book.
- Every book its reader.
- Save the time of the reader.
- The library is a growing organism.
