Not only do many want to publish autobiographies, but they expect to be picked up by the handful of traditional publishers out there. Some are going the self-published route. My response is unless you are rich, famous, or a celebrity, you are probably not going to be picked up by a traditional publisher. You can self-publish, but I doubt you will see many book sales unless you fall in the rich, famous, or celebrity categories.
I recently picked up a free ebook yesterday on Amazon by someone doing the self-published route. I haven’t started reading it yet. Let’s just say it’s not something I would normally read, but I picked it free. I will give it a go. I will start with the back blurb. I read what the author mentioned in his short introduction to the book. I will probably skim it as the author makes some wild claims in the book. I usually don’t take such claims seriously and am unlikely to take the author at his word.
