Whether you are quoting directly or paraphrasing information you found in a book, article, or website, you MUST acknowledge the source of the information. Within the body of your paper, this is called an Internal Reference Citation or Parenthetical Documentation. At the end of your paper, you should include a Bibliography of sources used or a Works Cited page. These list all books, magazine and newspaper articles, as well as websites that you used when creating your final product. Items on this page are listed alphabetically by the last name of the author or by the title if there is no author.
