Terms to Know
Common Knowledge
Information that is "common knowledge" are facts that can be found in numerous places and are likely to be known by a lot of people.
Example: John F. Kennedy was elected President of the United States in 1960.
This is generally known information, so you don't need to cite this fact, however, you must document facts that are not generally known and ideas that interpret facts.
Example: According the American Family Leave Coalition’s new book, Family Issues and Congress, President Bush's relationship with Congress has hindered family leave legislation (6).
The idea that "Bush's relationship with Congress has hindered family leave legislation" is not a fact but an interpretation. For interpretations of facts, you need to cite your source.
Quotation
Quotations use someone's words. When you quote, place the passage you are using in quotation marks, and document the source according to a standard documentation style.
The following example uses the Modern Language Association's style:
Example: According to Peter S. Pritchard in USA Today, "Public schools need reform but they're irreplaceable in teaching all the nation's young"; (14).
Paraphrase
When you paraphrase, you are using someone's ideas, but putting them in your own words. This is probably the skill you will use most when incorporating sources into your writing. Although you use your own words to paraphrase, you must still acknowledge the source of the information.
For examples of acceptable and unacceptable examples of paraphrasing, see our page on Examples.
