Often I receive books to format/convert without a copyright page. I think it’s best that you have one to protect yourself and increase the credibility of your work. And while I’m no lawyer, the following is commonly used by the vast majority of authors/publishers. I also recommend putting your contract info on the Copyright page in case someone would like to request permission or license your work!
By virtue of you publishing it, it’s protected by copyright, however if you do want to register your eBook with the Copyright office, you can do so for $35 if you e-file. The website is: https://eco.copyright.gov/eService_enu and you will need to have a PDF version of your book available to submit.
You should include something like the following on the copyright page of your eBook:
Copyright 2016 © [AUTHOR NAME]
All rights reserved. No part of this book may be reproduced in any form or by any electronic or mechanical means, including information storage and retrieval systems, without written permission from the author, except in the case of a reviewer, who may quote brief passages embodied in critical articles or in a review.
Trademarked names appear throughout this book. Rather than use a trademark symbol with every occurrence of a trademarked name, names are used in an editorial fashion, with no intention of infringement of the respective owner’s trademark.
The information in this book is distributed on an “as is” basis, without warranty. Although every precaution has been taken in the preparation of this work, neither the author nor the publisher shall have any liability to any person or entity with respect to any loss or damage caused or alleged to be caused directly or indirectly by the information contained in this book.
If your book is fiction, add this statement:
This is a work of fiction. Names, characters, places, and incidents either are the product of the author’s imagination or are used fictitiously, and any resemblance to actual persons, living or dead, events, or locales is entirely coincidental.
Hope that helps!
Happy new year – Brian
