The Five Laws of Library Science, authored by the eminent librarian and mathematician S. R. Ranganathan in 1931, stand as enduring principles guiding the philosophy and practice of librarianship worldwide. Rooted in the essential purpose of libraries to facilitate access to information and knowledge, these laws encapsulate the fundamental principles that govern the organization, management, and service provision within library settings. From the imperative to prioritize the utilization of library resources to the recognition of the individual needs of each patron, these laws serve as a blueprint for librarians to effectively fulfill their mission of serving communities, fostering literacy, and promoting intellectual inquiry. Each law reflects a commitment to efficiency, inclusivity, and adaptability, ensuring libraries remain vibrant and indispensable institutions in the ever-evolving landscape of information dissemination and education.
Historical Context Behind the Five Laws of Library Science
The historical context behind the Five Laws of Library Science is deeply rooted in the early 20th century, when libraries were undergoing significant transformations due to technological advancements, changing societal needs, and evolving approaches to information management.
S. R. Ranganathan, an Indian librarian and mathematician, formulated these laws in 1931 against the backdrop of rapid changes in the field of librarianship. Ranganathan recognized the need for a systematic framework to guide the development and operation of libraries, significantly when libraries were expanding their collections, services, and outreach efforts. During this period, libraries were transitioning from traditional repositories of books to dynamic hubs of information and knowledge. The proliferation of new media, such as newspapers, magazines, and audiovisual materials, posed challenges in cataloging, classification, and retrieval. Additionally, there was a growing emphasis on making libraries more accessible and responsive to the needs of diverse user groups, including students, scholars, professionals, and the general public.
Against this backdrop, Ranganathan’s Five Laws of Library Science emerged as a groundbreaking contribution to the field, providing librarians with a set of principles to guide their practices and decision-making. These laws helped librarians navigate the complexities of managing collections, organizing information, and providing services in ways that were efficient, equitable, and user-centered. Ranganathan’s work had a profound impact in India and internationally, influencing the development of library science and librarianship around the world. His laws continue to be taught in library science programs and serve as a foundation for modern library practices, demonstrating their enduring relevance in an era of digital information and evolving user needs.
Five Laws of Library Science
Dr. Shiyali Ramamrita Ranganathan formulated in 1928 the five laws of Library Science. These were published in a book in 1931. The laws of Library Science are as follows:
- Books are for use;
- Every reader his or her book;
- Every book its reader;
- Save the time of the reader;
- The library is a growing organism.
These laws emanated from his intense involvement in all aspects of library science, including his wide experience, deep study, and thinking. The essence and implications of these laws are now discussed:
1. Books are for use: The term ‘book’ should be interpreted broadly to stand document. Recognition of this law helps remove restrictions on the use of books, i.e., making library service accessible universally. The library aims to ensure maximum use of reading materials. The first law is to be achieved through the following factors:
- Services, usages, and accessibility: The greatness of a library is determined not only by the richness of its collection but by its services, usages, and accessibility. A few books kept in constant and extensive use are more valuable than thousands of books kept in a stately building. The Library schedule must be convenient for the reader. The large library should open its doors to readers on holidays for some time.
- Publicity: The librarian should give fair publicity about the services offered by his/her library. He/ She should always publicize and add a new addition to the library to inform his/her clientele what new materials have been acquired. The latest arrival should be displayed.
- Building: The library building should be attractive. The exterior should be inviting, and the interior should be well organized and decorated so that it could fascinate the readers or users. There should be proper lighting and ventilation, illustrations on the wall, colored walls, a neat and clean environment, and a soundless room that encourages the readers to study or read more and more times.
- Equipment: The library equipment should be neat and attractive. The book racks should not be so high. The reading room should be attractive, and the chairs and tables should be suitable for continuous reading.
- Open access: Access to the library shelf should be unrestricted so that the readers can go to the shelves and pick out the book most suitable.
- The co-operation of library staff: Staff should be congenial towards the readers and should always be ready to help the readers.
2. Every reader his/her books: The second law emphasizes in greater detail the implication of the first law as viewed from the side of readers. The service library should amplify the user’s demand and enhance the utility of book usage. The librarian should extend book usage through superfluous books. The second law is to achieve by the following factors:
- Book for all: The book should be for every type of reader, regardless of age, sex, race, caste, religion, etc.
- Book selection: The second law emphasizes the selection of books for ordinary people and physically handicapped ones. Books also have to take care of the newly literate.
- Inter-Library loan: The entire book resources of a country can be made available through inter-library co-operation.
- Catalogue or analytical entries: A book of composite and complex nature should be explained fully to readers by catalog or subject analytical entries.
- Open access: Books should be kept on open shelves so the user can easily handle the book whenever needed.
3. Every Book its reader: The third law, ‘Every book its reader,’ points out that the book is meant for the reader, not the filing stack room. It relates to finding out about every book in the library. Books cannot reach the hands of the readers on their own accord, so the librarian must bring the readers into contact with the books. The third law is to be achieved by the following factors:
- Proper cataloguing: Proper cataloguing can also help in the use of books. A classified catalogue with analytical entries for all the hidden subjects in a book will go a long way in this direction.
- Book selection: Book selection should be for all users. Books that are not likely to be demanded by readers should not be selected for procurement.
- Publicity: The librarian should draw the readers’ attention to those valuable books that lie unused and uncared for a long period. Besides, he must give prompt publicity to new arrivals of books. This could be done by inserting a notification in the press or by periodical circulars, notices, displays, etc.
- Open access: Open access to Bookshelves can also greatly help.
4. Save the time of the readers: Books should be made available to the readers without delay. This is the law that really tests the efficiency of the library. The methods of classification, cataloging, issuing of books, proper shelving of books, etc., all play an important role in saving the reader’s time. This law is to be achieved by the following factors:
- Classification: Books should be classified as quickly as possible after accessioning so that the books go to the shelves without any time lag. Efforts should be made to make the book available to the readers within a week of its arrival.
- Cataloguing: This catalogue should be done systematically so the readers can pick out what they want. A classified catalogue will be found more valuable than a dictionary catalogue, practically in special and academic libraries. However, a dictionary catalogue is more useful in public libraries.
- Changing methods: The methods of issuing books and receiving them when returned should be so that the reader does not have to spend much time at the changing or discharging counter. Newark or Browne methods can be widely used in the library.
- Shelving: The book should be so arranged on the shelves that not only can they be found easily, but the reader interested in a particular subject should be able to find them together.
- Open access: Open access saves not only the time of the reader but also saves librarians a lot of work.
5. Library is a growing organism: The library is an ever-expanding organization. The growth is of three kinds, and they are as follows:
- Growth in size: Every library grows with the acquisition of new materials. A newly started library has to grow in size rapidly to serve its clientele. Unlimited growth creates many problems. The most serious issue is finding adequate space and staff. Efforts should, therefore, be made to control the unlimited growth in size by continuously weeding out old and longer-wanted books.
- Growth in the number of readers: The growth shows how popular the library is and how well it serves its clientele. Growth in membership does not depend merely on the number of books available in the library but chiefly on the services offered by the library.
- Growth in staff: With the growth in size and membership, there has to be a corresponding growth in the staff. The efficiency of library service can be maintained only if there is adequate staff.
The librarian who would like to flourish in his career and be successful must keep the five laws of Library Science in mind. And the librarian who wants to maintain his library service fully must have to apply these laws in his/her library. These five laws may be considered the main motto of library science.
How do the Five Laws reflect the philosophy of library science?
The Five Laws of Library Science reflect the core philosophy of library science by emphasizing the principles of accessibility, service, efficiency, adaptation, and user-centeredness.
- Books are for use: At its core, this law emphasizes that the primary purpose of libraries is to facilitate the utilization of resources by their patrons. Libraries exist not merely as repositories of books and information but as active spaces where individuals can access, engage with, and benefit from the available materials. This reflects the philosophical belief that libraries should serve their communities’ informational, educational, cultural, and recreational needs, fostering lifelong learning and intellectual growth.
- Every reader his/her book: This law embodies the principle of inclusivity and equitable access to information. It recognizes library users’ diverse interests, backgrounds, and information needs and emphasizes the importance of providing a wide range of materials to meet those needs. By offering diverse collections that encompass various subjects, genres, formats, and languages, libraries uphold the philosophy that everyone should have the opportunity to find materials that resonate with their interests and support their learning and exploration.
- Every book its reader: This law highlights the essential role of librarians as intermediaries between users and information resources. Librarians serve as guides, advisors, and facilitators, assisting patrons in navigating the vast array of available materials to find those that best match their needs and preferences. This reflects the philosophical belief that librarians should be proactive in understanding and responding to the information needs of their communities, ensuring that users can access relevant and reliable resources to support their research, learning, and personal interests.
- Save the time of the reader: Efficiency and effectiveness are central tenets of this law, reflecting the philosophical belief that libraries should strive to optimize the user experience and streamline access to information. By organizing collections systematically, implementing user-friendly cataloging and classification systems, and providing efficient reference and assistance services, libraries aim to minimize users’ time and effort searching for materials. This aligns with the philosophy that libraries should be user-centered institutions that prioritize convenience, accessibility, and ease of use, thereby enhancing patrons’ ability to locate and utilize information effectively.
- The library is a growing organism: This law embodies the philosophy of continuous improvement, innovation, and adaptation in librarianship. It acknowledges that libraries operate within dynamic and evolving environments shaped by technological advancements, societal changes, and shifting information landscapes. Libraries must embrace innovation and emerging technologies and evolve their collections, services, and practices to remain relevant and responsive to the needs of their communities. This reflects the philosophical belief that libraries should be forward-thinking institutions committed to lifelong learning, experimentation, and growth, continually striving to enhance their capacity to serve and empower their users in an ever-changing world.
The Five Laws of Library Science encapsulate the philosophical principles that guide librarianship, emphasizing the importance of user-centeredness, inclusivity, efficiency, adaptability, and continuous improvement in fulfilling the mission of libraries to promote access to information, knowledge, and learning for all.
The Five Laws of Library Science, formulated by S. R. Ranganathan in 1931, stand as timeless principles that continue to shape the philosophy and practice of librarianship. These laws serve as guiding beacons, illuminating the path for librarians as they navigate the complexities of the modern information landscape. Rooted in the fundamental principles of accessibility, user-centeredness, efficiency, adaptability, and service, these laws underscore the essential role of libraries as vibrant hubs of knowledge, learning, and community engagement. As librarians uphold these laws in their daily endeavors, they remain steadfast in their commitment to promoting access to information, fostering intellectual inquiry, and empowering individuals to explore, discover, and grow. In essence, the Five Laws of Library Science encapsulate the enduring ethos of librarianship, reminding us that libraries are not just repositories of books and information but vital engines of progress, enlightenment, and societal empowerment.
