This navbox is getting quite large. On my browser it doesn't even fit on one page. According to WP:Navbox "should be kept small in size" and "Navigation templates provide navigation between existing articles" (emphasis mine). A "list of ..." article could have the complete list. The references cited on the talk page above could go there too. -- Brianhe (talk) 02:48, 20 July 2010 (UTC)
