Five laws of library science by S. R. Ranganathan in 1931:

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.

In 2004, librarian Alireza Noruzi recommended applying Ranganathan's laws to the Web in his paper, "Application of Ranganathan's Laws to the Web":

3. Every web resource its user.
4. Save the time of the user.
5. The Web is a growing organism.[3]
