When you google a definition, the first entry that pops up is a simple definition, followed by links to different dictionaries for further inquiry. I have been told that Google pulls its definitions from the Oxford American College Dictionary, but how would one cite that in a paper? I was thinking perhaps as follows, but I don't know... (The year given is the year that I have been told Google refers to in its definitions.) Would this work?
