When you use information from any source, be sure to cite it using a consist format.  Here are two options:

• APA Style Guide from Purdue University: APA overview (opens in a new tab)
• CSE guide from Colorado State Libraries' CSE (Name/Year System) (opens in a new tab)

As a general rule of thumb, be consistent and remember the purpose of citing your sources is so that the person reading your paper can retrack your steps and FIND the resource you used.
