Here’s support from ALLI, the Alliance of Independent Authors, for my claim that you SHOULD NEVER PAY SOMEONE TO PUBLISH YOUR BOOK. Yes, there are some reputable book packagers out there who will charge you for various services, but the chances that you will make back what they charge you are slim. YOU CAN DO THIS YOURSELF. This ALLI article explains why it is so easy to fall for vanity scams. Here’s an important quote:
Many vanity presses will try to persuade authors that they are incapable of producing a professional book without an expensive full-service publishing package. This is particularly effective on authors who may not be comfortable with new technology; the idea of handing off the details of publishing to someone who will take care of it for you is alluring.
Do not be fooled. You can start your book off with a very modest investment if you apply very basic skills to get it formatted and posted. Spend your money on a cover and an ISBN, not on thousands of dollars for “publication” you’ll never get back.
Maybe you’ll notice that I’m very passionate about this. I just hate scams.
