The Longman Dictionary of Poetic Terms by Jack Myers and Michael Simms. Longman, New York & London, 1989. (out of print)

The reason I find it so useful is for Appendix 1 & Appendix 2. Appendix 1 is a general list of literary andpoetic terms. If you want a list of "FORMS" of poetry they have sublists under the heading FORMS such as: fixed forms (alcaics, arte mayor, ballad, ballade, etc.), semi-fixed forms, stanzaic forms, etc. Appendix 2 is a list of "rhetorical, poetical, and logical devices." Unlike most dictionaries of poetic or literary terms, these appendices show how all the listings in the dictionary are grouped together. For a beginning writer if the "sonnet" is the only fixed form you know of, thumbing through an entire dictionary is daunting. With these appendices you can find all the others. (Andrea Brice)
