The Five laws of library library and information science books free download pdf is a theory proposed by S. Ranganathan in 1931, detailing the principles of operating a library system. Many librarians worldwide accept them as the foundations of their philosophy.

Save the time of the reader. The library is a growing organism. The first law constitutes the basis for the library services. Ranganathan observed that books were often chained to prevent their removal and that the emphasis was on storage and preservation rather than use.

He did not reject the notion that preservation and storage were important, but he asserted that the purpose of such activities was to promote use. Without user access to materials, there is little value in these items. Ranganathan refocused the attention of the field to access-related issues, such as the library’s location, loan policies, hours and days of operation, as well as the quality of staffing and mundane matters like library furniture, temperature control and lighting. The first law of library science “books are for use” means that books in libraries are not meant to be shut away from its users.

This law suggests that every member of the community should be able to obtain materials needed. Ranganathan felt that all individuals from all social environments were entitled to library service, and that the basis of library use was education, to which all were entitled. Librarians should have excellent first-hand knowledge of the people to be served. Collections should meet the special interests of the community, and libraries should promote and advertise their services extensively to attract a wide range of readers.

Everyone has different tastes and differences and we should respect that. This principle is closely related to the second law, but it focuses on the item itself, suggesting that each item in a library has an individual or individuals who would find that item useful. Ranganathan argued that the library could devise many methods to ensure that each item finds its appropriate reader. One method involved the basic rules for access to the collection, most notably the need for open shelving.

The third law of library science “every book its reader” means a library’s books have a place in the library even if a smaller demographic might choose to read it. This law is a recognition that part of the excellence of library service is its ability to meet the needs of the library user efficiently.

Ranganathan recommended the use of appropriate business methods to improve library management. He observed that centralizing the library collection in one location provided distinct advantages. He also noted that excellent staff would not only include those who possess strong reference skills, but also strong technical skills in cataloging, cross-referencing, ordering, accessioning, and the circulation of materials.

The fourth law of library science “save the time of the user” means that all patrons should be able to easily locate the material they desire quickly and efficiently. This law focused more on the need for internal change than on changes in the environment itself. Ranganathan argued that library organizations must accommodate growth in staff, the physical collection, and patron use. This involved allowing for growth in the physical building, reading areas, shelving, and in space for the catalog.

The fifth law of library science “the library is a growing organism” means that a library should be a continually changing institution, never static in its outlook. Books, methods, and the physical library should be updated over time. Gorman later repeated them in his small book, Our Singular Strengths .
