The five laws of library science: In Ranganathan's Day & In Today's World

What is the role of libraries in physical (as yesterday) / virtual access (as today), according to the implied meaning of Dr. S R Ranganathan’s Five Laws of Library Science (wherein 'book' is to be considered as information in any form and medium)? Here, is a chart adapted from: “Do digital libraries violate the Third Law? ” By Michle V. Cloonan & John G. Dove -- Library Journal, 04/01/2005

The Five Laws	Book Shelf (Physical Library) as in Ranganathan's Day	Hybrid Library (Physical and Virtual combo)	Virtual Shelf (Digital Libary) as today
I. Books are for use	Open the doors / shelf (no locks; except rare/special books)	Ask a Ranganathan scholar / expert (for lead send an email)	Open the gateways (reduce hurdles / limit the restrictions to access)
II. Every reader, his book	Every reader in the library must search/find and get his/her book		Every reader even outside the library must be able to search/find and access his/her book
III. Every book, its reader	Reach out the un-reached via marketing, publicity and out reach		Reach out the un-reached via marketing, publicity and out reach
IV. Save the time of the reader	Don’t waste the time of the reader; save the time by creating current awareness service and bibliographies		Don’t waste the time of the reader; save the time by creating current awareness service, such as RSS, social media alerts, and canned (microwaved) bibliographies
V. A library is a growing organism	Have a short term and long term plan for expansion in every physical way		Have a short term and long term plan for expansion in every virtual way
