OTexts will publish print versions of selected books that are on the OTexts online platform. When we identify a book that we would like to publish in print form, we will first ask the author for permission. If the author agrees, the book will be copyedited by our professional editing staff, and prepared for sale on Amazon. There will be no charge to the author for this work, and the costs will be recovered through sales revenue from Amazon.
The best way to get your book selected for print is to have lots of readers and an active community using the book.
