Google docs

I've been playing around with Google Docs presentations and I can see that this is easier than using, for example, powerpoint for a simple presentation, if several people are to be contributing to the presentation.

This could be used in libraries when library staff need to work together on a document, although it is very dependent on having fast internet connection that doesn't drop out. I really like that it keeps track of the changes that different people make, and when they make them. It makes it easier to go back to an earlier version and look at new changes.
