Obtain written permission to use any materials in your book that require official statements to be made upon reprint. For example, song lyrics, a commonly cited copyrighted material, often require a statement to appear such as "Blank", by "The name of the book author," "year of publications", was reprinted with permission from "name of publisher" and any other information required by that particular publisher.
Follow these statements on a page, adjacent to your title page, with a space, then the statement, "Copyright (followed by the copyright symbol and year) by your name.
Skip a space and start your own permission statement, starting with "All rights reserved, including the right to reproduce in any form or length."
Add any first or second reproduction requirements unique to your publication and make a statement that unauthorized reprint isn't allowed.
Include the name and contact information of the publisher of your book, or your own name and address, if self-published. This will guide anyone who'd like to reprint your work in the future.
