Any use of material created by another person must be properly cited (credit given). There are many different ways to cite (MLA, APA, Chicago, etc.), so be sure to clarify with your teacher as to the proper method. Below are some helpful citation creators for you to use.
**The key to any citation is to gather the information on any research source you consider. It is easy to look over an article early on in your study and decide not to use it only to later realize it has the 'perfect' quote to end your paper. Record titles, authors, sources, etc. for every work you read as you go. Even better...drop the information into one of the citation builders linked above and print or save the records as you go. What's the worse thing that could happen...You have it and don't need it?
