Why should citations be included in a paper or report

Not only to make it look more professional

As you write your term papers, it will be important for you to document where you obtained the information cited in your report. Many of the references you use will come from published sources. Some may come from electronic sources such as the World Wide Web, Melvyl and Harvest databases available through the UC Davis library, CD references and the like, and some may come from interviews. An important component of your writing will be the effective use of reference material. This skill will serve you well in writing papers of all types, not just those required for classes.
