The Prosody Guide
The Prosody Guide is written for the general user, yet is an excellent book for the study of poetic devices, specifically prosody. The site also offers the book for sale (on Amazon.com), but all parts of the book are available for free on this site. Chapter topics include: Versification, Rhyming, Closed Forms, Open Forms, Nordic Prosody, Alliterative Verse, Phonetic Rhetoric and Advanced Poetic Devices, and Phonetic Inequality. The author includes examples from literature to illustrate the different formats.
