A smart successful publisher usually doesn’t try to be all things to all readers. They focus their attention on reaching one or two niche markets such as children’s books. If you can identify the niche market that is most likely to be interested in your book then you can easily find a publisher that would be the best match for your work.
One of the easiest solutions of how to find a publisher is to look at books in the same genre you are working in and make note of who published those books. You can look at your own bookshelf, the library or visit online book sellers to find a publisher that’s right for you. Another strategy for finding a publisher would be to take advantage of current directories of book publishers. Some of these publishers won’t look at your work unless you have an agent so you may need to find a good agent before approaching large publishers.
