In 2016, Dr. Achala Munigal recommended the following changes to the Ranganathan laws due to the introduction and application of social tools in libraries: Gorman repeated these laws in Chapter 1 of his book Future Libraries: Dreams, Madness, & Realities, co-authored by Walt Crawford, and in Our Singular Strengths: Meditations for Librarians. The fifth law of librarianship, “A library is a growing organism,” means that a library must be a dynamic institution that is never static in its perspective. Ranganathan identified two types of growth: growth, which increases the quantity of objects in the library`s collection, and growth, which improves the overall quality of the collection through the exchange of documents.  Books, methods, and physical library need to be updated over time. You have to consider the growing physical space, but in the 21st century, that means the different format platforms that a collection can encompass.  The fourth law of librarianship, “Save the reader`s time,” means that all users should be able to find the materials they want quickly and efficiently. The practice of library science creates systems, services, workflows, guides, and frameworks for the benefit of user convenience.  Ranganathan said the fourth law, in turn, saves library staff time through practices such as centralized classification and cataloguing, documenting documents before they are sent to the library that ordered them, and mechanizing methods of obtaining information.  The second law of librarianship, “Each His Own Book,” means that librarians must serve a large collection of clients, acquire literature to meet a variety of needs, and contain no prejudice or judgment about what particular users want to read. Librarians need to respect the fact that everyone is different and everyone has different tastes about the books they choose. After the publication of the Five Laws of Librarianship, Ranganathan named children, the physically handicapped, artisans, newly educated adults, the mentally handicapped, working-class people, and those with niche interests as specific groups of potential readers served by the application of the Second Act.  In addition, A library collection should represent the community it serves.
 The third law of librarianship, “Every book is its reader,” means that all books have a place in the library, even if only a small part of the population wants to read them.  Ranganathan later clarified that the term “book” could be generalized to refer to any document.  In 1998, Michael Gorman, former president of the American Library Association, recommended the following laws in addition to the five Ranganathan laws: The first law of librarianship, “Books are intended to be used,” forms the basis of library services. This law means that books in libraries should not be kept away from users. Ranganathan observed that books were often chained to prevent their removal, and that the focus was on storage and preservation rather than use.  He did not reject the idea that preservation and storage were important, but stated that the purpose of such activities should be to promote use.  Without user access to documents, these elements have little value. With a focus on utilization, Dr. Ranganathan has drawn the attention of the field to issues related to access, such as library location, lending policy, hours and days of operation, quality of staff, and day-to-day issues such as library furniture and temperature control.
 In 2004, librarian Alireza Noruzi recommended applying the laws of Ranganathan to the Web: The Five Laws of Librarianship is a theory proposed by S. R. Ranganathan in 1931 that details the principles of operation of a library system. Many librarians around the world accept laws as the foundation of their philosophy.   In 2008, librarian Carol Simpson recommended the following changes to Ranganathan`s laws to reflect media wealth: Ranganathan also wrote about what he called “the law of thrift.” According to this law, tax revenues should generally not be allocated to books with limited audiences.  In 2019, Basheerhamad Shadrach proposed the Five Laws of Knowledge, which were adapted from those of Ranganathan.
