Wikis and Google Documents

For Wiki documents I looked at a health and fitness document and that is the one I would most like to contribute to. I can see how for example if one is setting up a camping trip a wiki document can help everyone involved add to or modify the plans and what to bring. I would not use this for my library job because I am a shelver. For a google document I created one entitled "Fitness and Exercising" and looked at other google documents to get an idea how to create one. I don't think that I would actually use this at home. Also, I would not use this at the library since I am a shelver.
