“It should go without saying that the more one knows how to do, the more one can do,” writes Lewis Turco in this fifth edition of The Book of Forms: A Handbook of Poetics. This go-to reference guide has been revised to aid the contemporary reader and writer, and includes classic rules of scansion, a Form-Finder index, and new examples and terms for all forms of poetry and verse. Heralded for Turco’s engaging style, this companion, sometimes referred to as “the poet’s bible,” defines, explains, and contextualizes basic concepts so any writer looking to challenge their writing can step up to the task.
