Wikis

I have just had a look at week 4- wikis, spending a great deal of time wandering around in Wookieepedia...is that a great name or what?
I can see wikis having great applications for libraries. My particular library system has 11 service points, so co-ordinating project teams has always been an issue. Setting up a wiki for a particular project would mean everyone gets all the information all the time. It would certainly save on travel and meeting times too. It was interesting to see a library system using wikis for their procedures. I imagine the editing would be restricted, but the instantaneous nature of the updates etc would mean everyone gets the information at the same time. Just the cost savings from photocopying and printing alone should encourage more libraries to consider a wiki as a procedure database.
