You can use your book's online preview to give potential buyers a look inside your book. You can also adjust the number of pages shown or turn preview completely off. Here's how:
1. Go to your dashboard. Find the book whose online preview you want to modify, then click the Sell My Book button next to it.
2. Navigate to the Privacy & Sharing tab.
3. Adjust your Book Preview settings in the Personal Storefront section. You can customize what is shown in your book preview by showing the first 15 pages, showing all pages, or no pages.
