The title is correct, and this is a quite cursory and anglocentric survey of poetry from Gilgamesh to Mary Oliver. Almost no poems are printed in their entirety, there is very little discussion of any depth about what poetry is, the author's opinions are given freely, and sometimes without any clear support. Nevertheless, if you have had no exposure to poetry, perhaps you are a high school student, and you read English, this is an entertaining and brief introduction that might lead you somewhere good.
