Amazon CreateSpace has both pros and cons and  is usually the first choice for first time authors. Pros are that it's really simple to upload and you have the option to have both an ebook and a printed copy available at the same time..BUT..

 

Consider the cons listed below:

• The quality of the overall book isn’t as high

• Their colored prints are very costly and could make cookbooks and children's' books impossible for some

• They don’t offer hardcover

• They don't offer landscape books 

• Their international shipping is extremely limited

• You will only get distribution with Amazon

• CreateSpace's automatically assigned ISBN gives them distribution rights to your book. The ISBN is forever owned by CreateSpace
