What protects the content of the book from unauthorized use?

• A. Copyright Law
• B. Trademark Notice
• C. ISBN
• D. Library of Congress Cataloging-in-Publication Data

Answer: (A)

Copyright law protects the content of a book from unauthorized use by granting the author exclusive rights to reproduce, distribute, display, perform, and create derivative works based on the original text, images, and layout. This protection arises automatically as soon as the work is fixed in a tangible form, like writing or printing. It covers the particular expression—the exact wording and arrangement of the book—not the underlying ideas, facts, or concepts themselves. While registration can aid in enforcement, it isn’t required for protection to exist. Because of this, copying or using the book’s content without permission would infringe on the author’s copyright.

The other options don’t provide this kind of protection. A trademark notice guards branding elements like logos and brand names, not the book’s content. An ISBN identifies a specific edition for cataloging and sales, not legal rights. Cataloging-in-Publication data offers bibliographic information for libraries and catalogs, not protection for the content.
