One use is when you are quoting an outside source but don't want include the whole passage. In this case, the ellipses show that some words were omitted. He's an example from Purdue OWL:
"If the original quote is too long and you feel not all the words are necessary in your own paper, you may omit part of the quote. Replace the missing words with an ellipsis.
Original Quote: The quarterback told the reporter, "It's quite simple. They played a better game, scored more points, and that's why we lost."
Omitted Material: The quarterback told the reporter, "It's quite simple. They . . . scored more points, and that's why we lost."
Make sure that the words you remove do not alter the basic meaning of the original quote in any way. Also ensure that the quote's integration and missing material still leave a grammatically correct sentence."
