“How do I protect my book idea from being stolen?” is a question I’m often asked.

My answer is usually two-fold.

First, once you have your words down on paper, you are protected by copyright law. So if you sent me (or a literary agent or an editor) your manuscript, you are already protected from anyone stealing your idea. If someone put out your exact words with their name on it, you’d have a pretty strong case for their plagiarizing your work.

However, remember that copyright law protects only your expression–the exact words-not the ideas. (Note too: You cannot copyright book titles. So someone can use your exact book title.)

Second, you have to realize that people you would send your book to–a publishing coach like me, or an agent, or an editor at a publishing house–have no reason to steal your ideas. We are way too busy doing our work (if we’re reputable, and most of us are), to take your work and run with it–especially if you’ve already developed it and are known somewhat for your idea. (There’s that platform thing again. If you already have a following around your idea, how on earth could I or someone else compete? Why would we want to?)

Also, we do have our reputations to protect. What’s in it for us if we take your idea?

Seth Godin, in his recent blog post, makes another excellent point. Book publishing is an industry based on buying ideas. “A company that likes buying ideas has a process,” Seth says. “They make it relatively straightforward and they have no upside in stealing from you. A company that isn’t in that business puts up barriers. They troll around trade shows looking for ideas to take.” (Seth adds that he doesn’t think there’s anything wrong with that, legally or morally.)

The people who might steal your ideas are not those in publishing, but people in your own industry. If your idea is complicated, patent it, Seth says. If it’s simple enough to dream up in a week, Seth says “the only way you’re going to protect it is to build it, fast and well.”

That is, develop it, get it out there to your following (through ezine articles, blog posts, or podcasts, for example), and get known for it. Then you can organize it into a book format you can publish (either by convincing a traditional publisher to publish you, or by self-publishing).
