Visuals such as graphs and tables should used to assist in communication, not take up space in order to meet minimum page requirements. Use them carefully and wisely. A good discussion and excellent samples can be located at the OWL website.
MLA uses the author-page method of citation. The last name of the author and the page number(s) from which the quotation or paraphrase is taken are placed in parenthesis and inserted in the appropriate place.
When referencing or summarizing an entire source, mention the author name and title in the body of your text. When quoting, paraphrasing, or summarizing a particular passage or idea of the original source, include the author name and page number in the parenthetical citation. However, if you mention the author's name in your text, include page number(s) only.
If a direct quote is fewer than four lines, infuse it into your own text and use quotation marks.
However, if a direct quote exceeds four lines, make the quotation a free-standing indented block quote and DO NOT use quotation marks.
If you have any endnotes, include them on a separate page before your Works Cited page. Entitle the section Notes (centered, unformatted).
