This is one of the most extensive and best-kept Library-Wiki's I've seen -- in this case from the IT Department of UCONN Libraries.

All you have to do is go to their "ITS Desk Main Page" to see what kind of job they've done. There's everything listed here from Work Schedules during Finals to information on "Out of Order Signs".

My only criticism -- and this I see all the time on Wikis -- is the weakness of the Main Page: it's overly heavy on instructions and overly weak on navigation aids to the rest of the site. (And yeah, I know there's the Left Navigation but since when in web design did we think this was enough -- for the Main Page?)

That said, this is a wonderful example of how to organize the often complicated documentation of a Library Department.
