All PLoS articles are freely available online, on the websites of PLoS and in the public archive PubMed Central, run by the National Library of Medicine. The articles can be freely redistributed and reused under a Creative Commons license, including for translations, as long as the author(s) and source are cited. PLoS also launched PLoS ONE, an online forum where people can publish articles on any subject relating to science or medicine. Three years after they were created, PLoS Biology and PLoS Medicine had the same reputation for excellence as the leading journals Nature, Science and The New England Journal of Medicine. PLoS received financial support from several foundations while developing a viable economic model from fees paid by published authors, advertising, sponsorship, and paid activities organized for PLoS members. PLoS also hopes to encourage other publishers to adopt the open access model, or to convert their existing journals to an open access model. 2004 > THE WEB 2.0, COMMUNITY AND SHARING [Summary] The term "web 2.0" was invented in 2004 by Tim O'Reilly, a publisher of computer books, as a title for a series of conferences he was organizing. The web 2.0 has been based on community and sharing, with a wealth of websites whose content has been supplied by users, such as blogs, wikis, social networks and collaborative encyclopedias. Wikipedia, Facebook and Twitter, of course, but also tens of thousands of others. The web 2.0 may begin to fulfill the dream of Tim Berners- Lee, who invented the web in 1990, and wrote in an essay dated April 1998: "The dream behind the web is of a common information space in which we communicate by sharing information. Its universality is essential: the fact that a hypertext link can point to anything, be it personal, local or global, be it draft or highly polished.
