Five laws of library science

S. R. Ranganathan, considered by librarians all over the world to be the father of library science, proposed five laws of library science. Most librarians accept them as the foundations of their philosophy:

These laws are:

1. Books are for use.
2. Every reader his or her book.
3. Every book its reader.
4. Save the time of the reader.
5. The Library is a growing organism.
