Animated Tutorial Sharing Project (ANTS) is "a collaborative project presently involving librarians in Canada and the United States, but open to librarians elsewhere. The goal of the project is to create a shared repository of library, research, and information literacy tutorials created using screencast software such as Adobe Captivate, Qarbon Viewlet Builder, Techsmith's Camtasia Studio, or similar products."
At the moment there seems to be more information about creating tutorials (including a discussion forum) than actual tutorials, but the advice & discussion seems useful in itself. http://ants.wetpaint.com/
