So far, we've discussed the Chicago Manual of Style's approach to ellipsis points. Other style guides for more-specialized audiences have different standards. The Modern Language Association of America's MLA Style Sheet governs style in academic writings associated with the humanities. It decrees that writers should use "three spaced periods" to signify ellipsis within a sentence, including a space before the first period. An omission of text following the conclusion of a complete sentence is indicated by four spaced periods, but with no space before the first period. If whole paragraphs are omitted between portions of a block quote, the MLA Style Sheet advises that the writer may indicate the magnitude of the omission by interposing "a single typed line of spaced periods."
