How do I show that I've removed text from within a quotation in APA Style?
If you remove words from the middle of quotation, use three spaced ellipsis points (e.g., . . .) to indicate the change from the original quotation (American Psychological Association, 2010, p. 172). If you remove text from the end of a sentence but continue quoting from the following sentence, use four spaced ellipsis points (e.g., . . . .) to indicate the removal of material from between the sentences (pp. 172-173). Start your quotation at the point where the text is relevant; ellipses are not necessary at the beginning or end of a quotation (p. 173). See "Ellipses-When and How?" from the APA Style Blog for more information.
