Yes. If your book is not in distribution, you can do it yourself. Log in to your account, click on your username on the top right corner, then click on "Dashboard" to go to your Author Dashboard. From there go to "My Print Books (POD)" and click on "Update Metadata" for the book you want to delist. Under "Who can Buy", select "Only me". Once you save your changes, your book will be available only to you for viewing and purchase.
If your book is in distribution, please write to us at firstname.lastname@example.org with the SKU number of the book you want to delist. The process of removal from partner sites is manual and may take up to a couple of weeks. If any of our distribution partners have purchased copies of the book, they will continue to list the book until their copies are sold out. We will not supply fresh copies to them after the book has been removed from distribution.
Pothi.com reserves the right to fulfill any orders of the book pending at the time of removal.
