If you list a reference in the reference list, you should actually cite that reference in your written work.

Why should I cite sources that are listed in my reference list?

Your reference list should only contain sources that you cite in your written work. If there are references that are not cited in your work, the reader would have no clue on why that reference would apply to your work.

How do I cite sources that are listed in my reference list?
