Iv’e previously self published a short novel (50,000 words) a few years ago. Nothing realy happened with it, the book simply vanished amongst the thousands of others just like it. I’m now considering rewriting and extending it into a full size novel, with the aim of getting published traditionally onto the book shelf. Would potential agents/publishers have a problem with this as they sometimes have with previously self published work, or could I count it as a separate and new novel?
