This book defines 74 basic forms of poetry, summarizes their histories, and quotes excellent examples. The essay on concrete poetry states that "concrete poems use space. They use sound. Instead of simply letting the words stand for something else, the words in the poem dramatize their meaning by the way they look. They draw attention to their physical appearance, ink on the page. The poem becomes a collage of words, letters, and other symbols that may or may not have something to do with the meaning we usually assign to them. [Concrete poets] see poetry as a visual of graphic art. They see it as something that can be abstract and that must be looked at in order to be understood. In trying to enhance the meaning of the poem, as well as to free the poem from what these poets see as its linguistic or verbal limitations, they have made typeface, symbol, shape, and the spatial relationships between letters, words and lines fundamental elements." -- Source of annotation: Marvin or Ruth Sackner.
