Library uses for wikis

libraries can use a a wiki foranything but the short list below is some uses from the wilis I looked at:
-reference/resource page
-Informational (what's going on at the library)
-Best practices (Internal)
-Readers advisory

I think it is interesting that libraries can use a wiki for practly any thing they need.

I thinks Youth services librarians could use a wiki to post and share program ideas.
