Have you bought it yet? If you are intending to be a published poet, and, like me, no one has heard of you, you need "2011 Poet's Market."
As a poet often writing with religious overtones, I need to know which publications, secular and religious, are open to such poetry. Some do not want to see any sort of religious poetry, and others are open, but with limits, and others welcome it. This book helps me avoid wasting my time, their time, and postage. By using this book, everyone is happy.
I have used this guide successfully to be published. It is thorough, packed with info. The articles found between sections help me see the process more clearly, strategies and what to avoid.
Also, if you are looking to get into the religious market, Poet's Market is just a start. It is decent, but only covers the largest publishers in this genre. You should also buy Sally Stuart's "Christian Writer's Market Guide," a very similarly structured book, the definitive guide for Christian writers.
I fully recommend the "2011 Poet's Market."
