These works are not all directly related to one specific anti-war movement. Books for children and younger readers are also included, along with works of fiction and nonfiction. Books about War themes either explicitly oppose war or have been characterized as having strong anti-war attitudes. By introducing frames of reference, they hope to promote discussion about significant facets of our society. They want to amuse. While all authors have these as their ultimate goals, war writers have additional, more subject-specific motivations for their writing.
