A quick intro to social bookmarking

Social bookmarking is an activity performed over a computer network that allows users to save and categorize (see folksonomy) a personal collection of bookmarks and share them with others. Users may also take bookmarks saved by others and add them to their own collection, as well as to subscribe to the lists of others. - a personal knowledge management tool …

The concept of shared online bookmarks dates back to April 1996 with the launch of Within the next three years online bookmark services became competitive, with venture-backed companies like Backflip, Blink,Clip2, Hotlinks, Quiver, and others entering the market. Lacking viable models for making money, most of this early generation of social bookmarking companies failed as the dot-com bubble burst.

The main features of any social bookmarking tool are

  • centralized storage and availability of web links (i.e., accessible from most any computer with internet connection)

  • the ability to organize web links in some way (tagging, categorizing, bundling, descriptions, etc.)

  • ease of use (little or no coding experience needed)

  • discovery (e.g., the ability to share, recommend, or discover web links from other users)

A few popular social bookmarking tools include:

CiteULike ( ) saves citation details, exports them in a few different formats, and aggregates journal articles. Sometimes called the " for the academic world". ( ) is a social bookmarking tool that allows users to save, recommend, and share bookmarks through networks. Users can bundle (categorize) web links as well as assign tags (keywords). Links can be publicly shared or private. A GIL record can be tagged in

Digg ( is similar to both and pageflakes in that it is social bookmarking. Digg provides categories as a controlled entry point and allows users to rate articles.

( is a social bookmarking site website that allows users to store searchable copies of websites; additionally users can share their website copies.

PennTags ( /) is social bookmarking for the University of Pennsylvania's catalog. An example of a record tagged in PennTags catalog (a Voyager catalog!)

Pines/Evergreen is anticipating tagging as a Fall 2007 enhancement; OCLC’s also has social bookmarking on their list of future enhancements.

StumbleUpon ( ) is a toolbar feature which allows for user recommendations and metadata entry (descriptions, etc.), and random discovery.

..and expanding beyond bookmarking…

Nines ( ) uses Collex “a collections and exhibits tool for the remixable web, to aggregate peer-reviewed online scholarship and allow you to collect, annotate, and share it with students and colleagues” and have partnered with libraries such as University of Virginia.

Pageflakes ( is an ajax driven site that allows a user to pull in and share multiple kinds of rss feeds and web sites including links, news sites, blogs, and more. pageflakes is actively developing its service to give users more features and greater functionality without sacrificing ease of use. To see a pageflake pulling in UGA's library content:

Netvibe ( ) is an ajax driven site that allows a user to pull in and share multiple kinds of rss feeds including links, news sites, blogs, and more. netvibes was a little earlier than pageflakes in development.

LibraryThing ( ) is a organizational service for materials such as personal libraries which provides means to organize, share, and discover resources. LibraryThing has recently developed widgets for use by libraries. Two academic libraries are testing.

SmartTech ( /): Georgia Tech’s institutional repository which includes user submitted content.

...and other social networking sites which are offer more expanded services

Academic Libraries using Social Bookmarking:

Griffin Tech

University of Michigan

University of Tennessee

University of Georgia Cataloging Department

Savannah Technical College

..and there's even a Library community devoted to academic libraries using web 2.0 technologies:

To the future:

Web 3.0/semantic web

The semantic web is an evolving extension of the World Wide Web in which web content can be expressed not only in natural language, but also in a format that can be read and used by software agents, thus permitting them to find, share and integrate information more easily.[1] It derives from W3C director Sir Tim Berners-Lee's vision of the Web as a universal medium for data, information, and knowledge exchange. At its core, the semantic web comprises a philosophy,[2] a set of design principles,[3] collaborative working groups, and a variety of enabling technologies.


So, if Web2.0 is about collaboration, ease of use (on the user side) then Web 3.0 is about taking information and the efforts of the Web 2.0 collaboration and using technology to extend possibilities.

Semantic web technologies(?)

Freebase ( ) is a collaborative site (i.e., social networking) which also uses metadata to assist in organizing content.


A Mashup is a web application which pulls together information using a variety of resources to produce a singular thing (movie, webpage, etc.).
