For all your marketing ideas, I recommend the Christian Writers’ Market Guide. This can be purchased from the Christian Writers Guild or on www.Amazon.com. This book lists over 1,200 Christian markets. Study the markets for children and then go on the various websites of the publishing houses to see their latest books and their guidelines.
Also, another way to learn what is selling in the children’s market is to go to your local Christian store and look at the books. Ask the owner or manager what books sell the best. This will help you to become familiar with your market. Also, obtain catalogs from the publishing houses that you think you might like to write for. Most of them will send you one free of charge if you e-mail and ask, or else you can pick them up at writers’ conferences. Also, you can obtain copies of children’s magazines and church school take-home papers by sending an e-mail, asking for their writers guidelines and a sample copy. For take-home papers ask for their theme list. However you should check their websites first to see how much of this information is listed there.
