Reservation of rights
Copyright is not the only statement that should be made in a book. There should also be a statement along the lines of “All rights reserved . . .” in which it is clearly stated whether any copying of the material is allowed, for example for use in a review.
It may be important to put a disclaimer in the book along with the copyright and rights statements, particularly with fiction where the author is using autobiograpical material. Such statements will often begin: “The characters and
events in this book are fictitious. Any similarity with persons living or dead is coincidental . . .” This will help get you out of trouble if someone sues for defamation thinking that a character is meant to be them.
This stands for International Standard Book Number and is issued in the country of first publication of the book. I publish in the United States so the ISBN I put in books is a US number. (Although plans are afoot for the use of UK ISBNs.)
Each version of a book needs its own ISBN; so if you publish a paperback and an ebook you need one for each. An ISBN means that the book can be traced for the purpose of ordering etc. Simply put it means that the book exists and can be found by anyone who wishes to find it. ISBNs have to be purchased from the agent who deals with them in any particular country, and are expensive in small numbers. If you publish with 4 Square Books they cost nothing.
If you quote someone else’s work in your book you must credit them and you may have to obtain their actual permission. There are some conventions attached to this regarding how much you are quoting and so on.
