When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "New World Encyclopedia",
   title = "Petrology --- New World Encyclopedia",
   year = "2008",
   url = "\url{http://www.newworldencyclopedia.org/entry/Petrology?oldid=682247}",
   note = "[Online; accessed 24-November-2009]"
 }
