While you are writing you essay you have to write down all the used books, links, documents and information. Then you have to write them in an alphabetical order and to put them on the last page of your essay.

To reference something, you would make a works cited page. In doing this, you should place all sources in alphabetical order and in the correct format. You can find more information here: http://telecollege.dcccd.edu/library/mod...
