Some time ago, I submitted an unsolicted article to 'Punch' magazine. I never heard a peep from them but guess what? Two weeks later my article appeared, rewritten a little but clearly recognisable to me as mine without a shadow of a doubt. As the article itself was not my finest work, I put it down to experience. Today upon following a link from this forum I saw on a Publishers website the comment 'Further, in receiving a submission, we do not assume any duty not to publish a book based on a similar idea, concept or story' which I translate as 'we may steal it.' Now I have been putting a book together for some time and it is nearing completion, my concern is if I send it out to publishers, especially if I send it to a few, and it gets rejected but mysteriously reappears later on, what protection is there against this? (Apart from cost prohibitive attempted enforcement of copyright law) How common is content theft of this nature?
