Robert Hauptman writes about documentation and its purposes. He also writes about the history of  and how the concept dates back to even the ancient times all the way to the present. He discusses that documentation is meant for six different reasons, that being: acknowledgement, attribution, tracing, validation, protection and commentary. Haputman tells his audience that citations are a way of giving credit to the source that you have used. He argues that “scholars who are experts don’t need to spend time crediting because they are the source, whereas the inexpert needs to credit all their sources.” Its always right to give credit to work you used in your own to show the previous author that you acknowledged them and built upon their ideas.
