When citing a web site, limit the address to nationalgeographic.com. Don't recite the www or any /slashed additions. But, do give the full web address to the home page (i.e., Mothers Against Drunk Driving at madd.com). Don't be afraid to cite as often as you can.
Formulate a source citation for the following sentence taken from Time Magazine, Oct. 19, 2009, p. 16: "Less than 20% of schools cook school lunch from scratch; many rely on packaged reheatable foods."
