McDermott, I.E. "All A-Twitter About Web 2.0: What Does it Offer Libraries?". Searcher v. 15 no. 9 (October 2007) p. 34, 36-7, 39.

This article offers a nice overview of several different free, web based tools that can be beneficial to libraries. Some of the tools included in this article: Facebook, de.licio.us, Flickr, YouTube. A brief "how to get started" section, as well as ideas of potential applications for each tool are discussed.

Snipes, Phyllis R. "Folksonomy vs. Minnie Earl and Melville". Library Media Connection 25 no. 7 (April/May 2007) p. 54-6.

While published in a School Library focused journal, this article makes points and raises ideas that are relevant to academic librarians as well. The impact of Web 2.0 Tools, and the tech skills of current high school students are discussed in terms of information literacy skills. The author points out the importance of understanding user needs, and assessing the impact of Web 2.0 activities in a library.

I'm going to quote a line from the abstract I found in the Library Literature database, because it sums the article up nicely in 2 sentences.:
"This article looks at si different technologies: instant messaging, weblogs and RSS, wikis, podcasting, photo sharing, and VOIP. Each entry offers a definition of the tool/technology, its uses in a library, audiences that are currently using it, and a selection of helpful articles and websites."

Stephens, Michael and Rachei Singer Gordon. "Priceless Images: Getting Started with Flickr" Computers in Libraries vol. 26 no. 10 (November/December 2006) p. 44-5.

The authors of this article point out that a great benefit of the web is it's graphic nature and visual orientation. An easy (and free) way to take advantage of this benefit is by using Flickr for outreach and patron interaction.

Rethlefsen, Melissa L. "Tags Help Make Libraries del.icio.us." Library Journal vol. 132 no. 15 (2007) p. 26-8.

The author points out ways that tagging tools can "help librarians bridge the gap between the library's need to offer authoritative, well-organized information and their patrons' web experience." The best of both worlds? Library style organizationmeets patrons' Google style expectations.

Packi, Thomas. "A del.icio.us Way to Use Bookmarks". Information Today vol. 24 no. 4 (April 2007) p. 36-7.

Another article about social, web based bookmarking tools. This one highlights some of the benefits of sharing bookmarks, and what users can learn from the tagging tactics of others.
