I am a new author preparing to publish my first non-fiction book, and have several more books in the works. I want to get a traditional publisher. I read that creating an online presence will help an agent to take me seriously. Will posting work on writer’s websites, writer’s clubs, etc, help me gain exposure? Is there a risk of anyone stealing my work? What about my manuscript? I am a little worried that putting my work out there without copyright would put me at risk for trouble later. But copyright is usually something the publisher does for you? Right? What if my articles contain excerpts from my book?
