Mousaion 28(2), 1-16.00272639http://hdl.handle.net/10413/10974Ranganathan’s five laws of library science were first published in 1931. Although initially devised for the Indian context, these laws have been adapted – in form and spirit – by libraries all over the world. With the emergence of new librarianship models such as Library 2.0, most practitioners wonder whether the laws still hold. This study used critical documentary analysis to investigate the relationship between the Library 2.0 principles and Ranganathan’s fifth law. The authors conclude that this law, like the other four, remains applicable in most instances. However, some scenarios require careful consideration and adjustment of the fifth law.enRanganathan, Library 2.0, five laws of library science, Web 2.0.Peer reviewed journal article
