Amazon book publishing is a service offered by the online retailer Amazon.com. The service allows authors and publishers to self-publish their books electronically on the Amazon Kindle platform. Although there are many benefits to using Amazon book publishing services, there are also some key factors to consider before self-publishing on Amazon. First, it is important to consider the cost of self-publishing on Amazon. While there is no charge to publish your book on Amazon, you will be responsible for the costs of formatting and converting your book into the Kindle format, as well as any editing or proofreading fees. In addition, you will need to purchase a ISBN (International Standard Book Number) for your book, which can cost around $100. Finally, you will need to create an account with Amazon CreateSpace, which is the printing arm of Amazon.com. Creating an account with CreateSpace is free, but you will be required to pay for the cost of printing and shipping your book once it is published. Overall, self-publishing on Amazon can be a great way to get your work out into the world; however, it is important to be aware of the costs involved before making the decision to publish electronically.
