If you are using more than one volume of a multivolume work, e.g. an encyclopedia, cite the total number of volumes in the work. You do not need to include page numbers in your citation as you will include the volume and page numbers in your parenthetical reference. If you are using a single volume, cite the number of the volume and page numbers in your citation and the parenthetical reference need only include the page number not volume.
