You should provide a reference or citation whenever you introduce a new concept, explanation, fact, or statistic from another source. By doing so, you give credit to the original source and provide evidence that you have carried out your own research. If you are not certain about a particular source, be sure to ask your professor.
You do not have to cite facts, events, dates and concepts that are considered to be common knowledge.
Common knowledge can vary across cultures, academic disciplines, or peer groups. Since common knowledge in one subject area may not be considered common knowledge in another, it is important to consider these questions when deciding if something should be cited:
If you have doubts about what may or may not be considered common knowledge in your discipline, be sure to speak with your professor.
Remember that common knowledge in one subject area may not be considered common knowledge in another. When in doubt, the safest thing to do is to cite your source.
(probably don't need to cite in your discipline)
(always need to cite, no matter what discipline)
