how many lines does a quote have to be to be set off or indented?
Prose or verse quotations less than four lines long are not indented. For quotations of this length, use the patterns described above. Indent longer quotations in a block about ten spaces in from the left margin; when a quotation is indented, quotation marks are not used. The MLA Handbook (1995) recommends that indented quotations be double-spaced, but many instructors prefer them single-spaced.
