Main documents such as books and journals cited in Harvard style papers have to be italicized for easy tracing by the readers
. At the end of Harvard style papers a list of references should be included with all the used sources arranged in an alphabetical order. The reference list in Harvard style papers should have the author's names, date of production of source, name of editor, title of source in italics. It is good to note that a title and sub-title should be divided by a full colon, and the publisher and place of publication should also be included.
