"If you fail to acknowledge borrowed material, then you are plagiarizing. Plagiarism is literary theft. When you copy the words of another, put those words inside quotation marks, and acknowledge the source with a content note (using parentheses). When you paraphrase another's words, use your own words and your own sentence structure, and be sure to use a content note (using parentheses) giving the source of your idea. A plagiarist often merely changes a few words or simply rearranges the words in a source." -Harbrace College Handbook

The following is a passage from Page Smith's A New Age Begins: A People's History of the American Revolution:

    So ended the confused, tension-filled and finally bloody encounter that is known as the Boston Massacre. That it was no worse is a tribute to the British military discipline and coolness of Captain Preston. It is also a tribute to the patriot leaders, who kept the mob from exploding into greater violence. Finally it is a tribute to Thomas Hutchinson,  who acted with great decision and courage. But last of all, it is a testament to the folly of the English government in adopting policies that could make the colonists so hate the  mother country that such violence was inevitable.

When to Cite
Suppose you wrote in a paper: The Boston Massacre was inevitable considering the folly of British policies toward the colonies. Here you must cite a source, even though you are not directly quoting the author, because the information you give is the interpretation and understanding of a particular author. The citation should be placed immediately after the sentence.

Suppose you wrote in a paper: The Boston Massacre demonstrated the folly of the English government in adopting polices that could make the colonists so hate the mother country that such violence was inevitable. You must enclose the underlined material in quotation marks because it is taken directly from the book. A good rule: If you copy more than three consecutive words of text, put those words within quotation marks. The citation should be placed immediately after the quotation.

At the end of each paragraph, please cite the general source for historical information contained in that paragraph. This means that nearly all paragraphs in your paper, except where you are introducing the topic or offering conclusions that are your own, should have some citation.

How to Cite
     1. You may do internal notes, end notes, or footnotes. The format will be the same for internal notes, end notes, and footnotes (except that internal notes will have parentheses).
     2. The first citation must be complete. For example: Page Smith, A New Age Begins: A People's History of the American Revolution (New York: Penguin Books, 1965), 342.
     3. Thereafter, the citation may be abbreviated, for example, Smith, 342. If you are using more than one book by Smith, an appropriate abbreviation would be: Smith, New Age, 342.
     4. If you cite the same source in a following note, you should use Ibid., followed by the page number. If you cited Smith twice in a row, for example, the second time you would write Ibid., 343.

Bibliography
In addition to footnotes, endnotes, or internal notes, your paper must have a bibliography. In a bibliography the works cited in the paper are listed in alphabetical order by the name of the author. Style and punctuation differ for bibliographic entries. The bibliographic entry for the work used as an example above would be:
