 When we write an academic essay, we use journal articles, books, e-books, websites and other sources to support our discussion argument. We need to acknowledge our sources throughout our academic essay. This is how we do it, in CDU Harvard style. We cite our sources in text, which is called an in-text citation. In an in-text citation, we just use the surname of the author and the year of publication. If your citation is in brackets, use an ampersand between authors' names. If the author's names are part of the sentence, use the word end. You must provide a full reference for every source you cite in text. This list goes on a new page at the end of your essay. The list must be left aligned and in alphabetical order. For more guidance, go to the CDU Harvard referencing guide.
