How do you write ellipses within a quotation?

An ellipses means material has been omitted. At the beginning or in the middle of a quotation, use three periods in succession to show that material has been left out. (Most if not all modern word processing software will automatically reformat the three periods with a special spacing. If you're using an old typewriter, type period, space, period, space, period.) If you've composed a complete sentence but intentionally are leaving out additional, uninimportant information and following this with your own words, use only three periods. If on the other hand you're ending the sentence with the partial quotation, use the three periods for an ellipsis and add an additional period for the period.
