Dr. S. R. Ranganathan’s Five Laws of Library Science are the five pillars of the foundation of librarianship. These five laws have entered their 100th year, inspiring generations of librarians. Forty-seven studies covering Ranganathan’s Five Laws were collected from different online sources. Only 30 studies were found relevant to use for the study. The study determines how the five laws have inspired generations to apply them in various fields of study. As a result, the Five Laws have been applied to information and knowledge management, social media, technology, business, marketing, and web resources. It is also found that the use, user, time, form, growth, visibility, software and relevancy to manage information business are the core elements of the five laws. This study critically examined modifications and extensions of the “Five Laws” theory and proposed new theories in the dynamic nature of libraries.
