Final answer:
The ISBN-13 and ISBN-10 on a book serve as unique identifiers specific to each edition and variation of the book, helping to distinguish it from other books.
Step-by-step explanation:
The codes ISBN-13 and ISBN-10 on a book convey d) Unique identification for the book. The International Standard Book Number (ISBN) is a unique numeric commercial book identifier that helps to accurately identify books and distinguish them from each other. The ISBN is assigned to each edition and variation (except reprintings) of a book. For example, a paperback and hardcover version of the same book will have different ISBNs, as will a PDF version, an enhanced textbook, or a digital version of the book.
An ISBN-13 has 13 digits, which are divided into five parts: the prefix element, the registration group element, the registrant element, the publication element, and the check digit. ISBN-10, the older format, follows a similar structure but includes only 10 digits. It's important to note that neither the author's name, the publisher's address, nor the title of the book are specifically conveyed by the ISBN. An ISBN does include a segment corresponding to the publisher, but it will not give out the address. The original publication year can sometimes be deduced from the ISBN if the publisher has embedded it into the registrant element or publication element, but it is not specifically a part of the ISBN design.
