The web 2.0 refers to the interactive, user centered design of the World Wide Web where users not only access the web content but at the same time generate the web content. The term "Web 2.0" was coined in 1999 by Darcy DiNucci. Its rise and popularity began in 2004, when O'Reilly Media and MediaLive organized the first Web 2.0 conference. In the opening remarks, John Battelle and Tim O'Reilly outlined their definition of the "Web as Platform", where software applications are built upon the Web as opposed to upon the desktop. They further argued, that "customers are building your business for you". Users generating the content (in the form of ideas, text, videos, or pictures) could be "harnessed" to create value, they argued. O'Reilly et al. compared Web 2.0 with what they called "Web 1.0". They associated Web 1.0 with the business models of Netscape and the Encyclopedia Britannica Online (Wikipedia, 2010).
At the moment there is a hot debate, questioning the existence of web 2.0. Many argue that the web 2.0 is not a new phenomenon but the very features of web 2.0 were already available on amazon.com as early as Amazon came into existence. for application of web 2.0 in libraries you can go through under attached article.
