What needs to be cited?
  • Another person’s words
  • Another person’s ideas
  • Another person’s organization
  • Another person’s judgments and unique opinions
  • Visual information
  • Information from a company or organization rather than a single individual-- like a government Web site
  • Information like lectures, personal interviews, emails, discussion groups
  • Numerical information like statistics, amounts, and dates that are not common knowledge
  • Bulleted lists which appear in a source
What does not need to be cited?
  • Common Knowledge
  • Information that appears in various sources and is known to most educated people. For example, the U.S. went to war in Iraq in 2003, or Columbus discovered America.
  • Information that is well known in a field of study. For example, most medical researchers believe heredity plays a role in diabetes. As a rule of thumb, if you see the same idea in three different sources, it is probably well known in the field you are researching.
  • Facts—information that is not questioned and is found in many different references, like encyclopedias. For example, the Civil War ended in 1864 and Robert E. Lee was a Southern general.
  • And your own ideas. ("Knowing")
