Citing is the process of giving credit to the sources you used to write your paper. Citations
can be located in the text or at the end of the work in a bibliography. Sometimes it can be difficult
to figure out what needs to be credited.
Use this rule: If you knew a piece of information before you started
doing research, generally you do not need to credit it. You also do not need to cite
well-known facts, such as dates, which can be found in many encyclopedias. All other
information such as quotations, statistics, and ideas should always be cited in your papers.
