If the author’s name is included in the text, then add the page numbers for the source in parenthesis at the end of the sentence or quotation. (MLA Handbook 216-217)
Example: Cross writes that Austen’s writing has both the “humor and technique of a Shakespearean comedy” (28).
If the author’s name is not included in the text, add the author’s last name followed by the page number in parenthesis at the end of the sentence or quotation. (MLA Handbook 216-217)
It has been stated that the humor and technique of Austen’s writing is similar to that of a Shakespearean comedy (Cross 28).
If the source does not have an author or has more than one author, follow these guidelines:
You do not need to give sources for familiar proverbs, well-known quotations, or common knowledge, but if in doubt, cite the source!
If a quotation is longer than 4 lines, separate it from the rest of the text by beginning a new line and indenting one inch from the left margin. Double-space the quotation without adding quotation marks (MLA Handbook 94).
Early in the story, the young boys fill their pockets with stones, an ominous foreshadowing of the attack at the end of the story:
Although the villagers had forgotten the ritual and lost the original black box, they still remembered
to use stones. The pile of stones the boys had made earlier was ready; there were stones on the ground
with the blowing scraps of paper that had come out of the box. Mrs. Delacroix selected a stone so large
she had to pick it up with both hands …Tessie Hutchinson was in the center of a cleared space by now,
and she held her hands out desperately as the villagers moved in on her. (Jackson 205)
