If you use other people's ideas you want to give credit to them by referring to them. This process is called citing. You cite each item in two places. In your report you give a short in-text citation after you refer to an article, book, blog, etc. AND at the end of your report . At the end of your report you create a list of all the items you used in your report under the heading, Reference List.
