Which data item helps locate the Encyclopedia of Counseling in international catalogs?

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

Answer: (A)

Knowing how bibliographic identifiers work helps locate a specific book in catalogs around the world. The ISBN, or International Standard Book Number, is a unique code assigned to each edition and format of a book. Because it uniquely identifies that exact edition, libraries, bookstores, and databases can retrieve the precise item across international catalogs simply by searching the ISBN. Other options don’t serve as reliable global search keys: copyright law and trademark notices are legal or branding information, not bibliographic identifiers; while Library of Congress Cataloging-in-Publication data provides cataloging metadata, it isn’t a universal, edition-specific identifier used by international catalogs to locate the item.
