Punctuation goes inside the quotation marks.

Story is that this rule was created in the days when a period (full stop) could be physically lost in a row of type if it were outside the closing quotation mark. Dunno if this is true or not; perhaps Pfranz could tell us. As far as I'm concerned the primary rule is that the punctuation goes inside the quotation marks if it is part of the quotation.
