You need to cite your source whenever you are incorporating an idea or fact into your work that is not your own. This goes for quotes from books or articles, data sources and statistics, and any paraphrasing you may be doing from other sources. The point of citing is two-fold:
1. To attribute others' ideas
and 2. To help the reader be able to find where you got those ideas from.
Each type of source that you cite will have different requirements as to what information is needed to cite the source properly. You can find more on these proper citations by using the links below.
