Copy quotations carefully, with punctuation, capitalization, and spelling exactly as in the original.
Use quotation marks; don’t rely on your memory to distinguish your own words from those of the source. Identify the note as a quotation.
Use square brackets if you introduce words of your own into a quotation or make changes in it, and use ellipses if you omit material. If you later incorporate the quotation into your essay, copy it faithfully—brackets, ellipses, and all. (13b)
If the quotation appears on more than one page of a print source, use a slash ( / ) to indicate where one page ends and another begins.
