According to the South Dakota Board of Regents Policy 3:4
Plagiarism (which) is defined as, but is not limited to, the following:
Common knowledge: facts that can be found in numerous places and are likely to be known by a lot of people.
This is generally known information or “common knowledge” and therefore, you do not need to document this fact.
When to cite:
Also, check out the LibGuide below for additional information . . .
Write your own summary without looking at the original text, but remember to cite your sources.
When taking notes, write down the source information and put it next to the notes so you can easily cite the source.
Don’t wait until the last minute to write your paper.
Don’t just copy ideas and words from a source – record your own reactions and thoughts as you do your research. This will give you starting points when you write your paper.
