It is not easy to add multivolume works and the contributions by various writers within them in, as the example below illustrates. Use the Edited book and Contribution reference types.
1 First, add the work as an Edited Book. If the multivolume work only includes the writings of one author (for example, an anthology of all of the author's writings), add the work as a Collected work.
2 Add the Contribution, making sure to include the volume number.
