If, for example I have this sentence:
He started a website, SaveSandy.org, however this website is currently “Under maintenance”.
Does the period go on the outside, or the inside of the quotation marks? I've seen various newspaper and web articles with it on the inside, and on the outside.
Which one is it? And if possible, preferably give me a source, to verify your claim? Also, I'm talking about American English, not British. Thanks.
