Some students believe that you only need to credit a source if you use its exact words, but this is not true. Any fact that is not common knowledge (like "George Washington was the first President of the United States") needs a reference to the source. Here are some ideas from an article on teenagers and sleep from the newspaper called the Philadelphia Inquirer. Even though these are not the exact words of the source, it is never acceptable to write as follows:
Today's teenagers can easily have their biological clocks thrown out of alignment. This occurs because the changes of puberty make it easy for teenagers to stay up late at night, but hard for them to get up in the morning.
Notice, that this passage is incorrect, even though we have put the ideas from the source into our own words. The right way to refer to this information would be as follows:
Today's teenagers can easily have their biological clocks thrown out of alignment. This occurs because the changes of puberty make it easy for teenagers to stay up late at night, but hard for them to get up in the morning (Phillips H1).
The parenthetical reference gives the last name of the author (Phillips) and the page number (section H, page 1) of the article. You would also need a corresponding entry in a "Works Cited" section at the end of the paper:
Phillips, Shelly. "Sleepless in School," Philadelphia Inquirer February 1, 1995, H1, H3.
