What is Library 2.0?
There are many definitions of Library 2.0. Simply put, it is the ongoing response to Web 2.0, a participatory, networked, interactive, and collaborative community of web users. The term "Web 2.0" was introduced by O'Reilly Media in 2004 as shorthand for a "second generation" of web applications that incorporated increasing amounts of social interaction and online collaboration. Similarly, "Library 2.0" is the shorthand for a vast array of initiatives in all types of libraries to incorporate the tools for online collaboration into new ways to deliver effective library services.
As for the implications for school libraries, the array of presentations at the 2007 National Conference relating to 2.0 issues as well as the posts on the AASL blog signal the importance of the concepts in school libraries.
Teens are heavily into social networking tools, and younger school children are developing the skills to use the interactive sites early on. ALA's Young Adult Library Services Association has prepared three related resources: 1) Social Networking Toolkit for Librarians, 2) 30 Positive Uses of Social Networking and 3) a pamphlet, Social Networking a Guide for Teens, all available from the YALSA wiki.
A recent study from the Pew Internet & American Life Project, "In Search of Solutions: How People use the Internet, Libraries, and Government Agencies to Find Help," suggests that those people who are "well-wired" are also heavier library users. Research from the UK, Information Behaviour of the Researcher of the Future (PDF format; 1.67MB) shows that "research-behaviour traits that are commonly associated with younger users – impatience in search and navigation, and zero tolerance for any delay in satisfying their information needs – are now becoming the norm for all age-groups, from younger pupils and undergraduates through to professors." In other words, what we're using on the Internet in general, we want in our library services, too.
