Oh my dear Wiki....
I think Wiki is a wonderful tool for public libraries to educate their users about their resources and information. It is even more useful for internal use in libraries for planning and communication between staff. We have a Wiki at Olney library which is very informative and keeps staff with the latest library news and events, it encourage us to add content and exchange ideas on a different subjects. I like the SJCPL and Book lovers wikis for their simple structures and educational resources they provides to their communities. Wiki is a must for public libraries and it opens up a new possibilities for collaboration between libraries and their users.
