how old to publish a book?
18 if you want to do it entirely unaided. You need to be 18 to enter contracts with most big-name distributors such as Amazon, iStore, etc. If you just mean have someone print a bunch of copies so you can sell them yourself, or if you are going to provide them on your web site, you just need to be old enough to write. Best of luck. Check out Guy KawasakiÊ»s book APE: Author Publisher Entrepreneur.. Views Â· View Upvotes.
