The Internet (from Wikipedia)  The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide.  It is a network of networks that consists of millions of private, public, academic, business, & government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies.

The World Wide Web (from Wikipedia)  The Web is a system of interlinked hypertext documents accessed via the Internet.  With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them by using hyperlinks.  Tim Berners-Lee and his team originated the WWW.

Web 2.0  Who coined the phrase? Tim O’Reilly of O’Reilly Media and MediaLive International  Web 2.0 applications are built for user- added content  Before, a web manager added content to a website but the exchange was one- way  Today, anyone with Internet access can add content to a Wiki, Blog or other social networking site

Web1.0 vs Web2.0  Term Web2.0 suggests a new version of the Web, but actually it does not refer to an update to any technical specifications. Rather it refers to cumulative changes in the ways software developers and end-users use the Web.  It is the difference betw Britannica online and Wikipedia  In Web 1.0 content was written, edited and published by a select group of people much the same way books are published.  In Web 2.0 anyone can add to the collective pool of knowledge and anyone can access it.  Web 2.0 Applications can run on mobile devices, not only PCs

O’Reilly quote: people “A core concept of Web 2.0 is that people are the content of sites are the content of sites. That is, a site is not populated with information for users to consume. Instead, services are provided to individual users for them to build networks of The content of a site friends and other groups (professional, recreational, etc.). The content of a site then, comprises user-provided information that attracts new members of an ever- expanding network.”

What is Library 2.0? User participation/collaboration Reaching new users Constant & purposeful change Embracing new technology Not just a technology shift, but also a cultural shift. Library services taken to the user

Why library2.0?  Users have changed Want almost instant gratification Cell phones - texting 24/7 services expected Move to self-service information Belief in First World that the ‘Web’ is the library Increasing visibility of individuals online e.g. MySpace; Flickr; etc. People are going elsewhere to connect to information & community (not libraries) Library info needs to appear where users spend their online time e.g. Google, portals, virtual learning environments or learning communities
