This is the third in a series of posts in which I recommend books for aspiring and published writers. Each post covers a category, including biographies/autobiographies, magazine writing, how-to-write books by notable writers, books on the business aspects of writing, fiction how-to, and more.
These books cover agenting, contracts, and related matters. They are a must if you don't use an agent, and worth reading even if you do.
How to Be Your Own Literary Agent: The Business of Getting a Book Published, Revised edition, by Richard Curtis (Houghton-Mifflin, 2003)
Be Your Own Literary Agent: The Ultimate Insider's Guide to Getting Published, Third edition, by Martin P. Levin (Ten Speed Press, 2002)
The Career Novelist: A Literary Agent Offers Strategies for Success, by Donald Maass (Heineman, 1996)
You can find most of these books at your local bookstore or at Amazon.com or other online retailers. For a few of the out-of-print titles you will have to go to eBay or a used book store.
