I found the Library Success wiki to be helpful. I especially liked the ideas of where to donate discarded books.
I use wikipedia somewhat often. I use it when people need a series order, as well as for looking for information about a certain town, etc.
I like how when something is inaccurate, it is usually corrected (as far as I know). I love that wikipedia has links within the article. It was interesting to look at the history tab. I never went into this. I did not know that you could contact the contributor. I never thought about it.
Somewhere in the history tab I saw a something posted by vampireken about TR being haunted.
