Both ISBN-10 and ISBN-13 numbers exist. ISBN-10 numbers are 10 digits long and were used prior to 2007, while ISBN-13 numbers are 13 digits long and have been in use since then. The transition to ISBN-13 was made to accommodate the increasing number of books being published and to provide a more comprehensive and unique identification system for books. **

The main difference between ISBN 10 and ISBN 13 is the length of the numbers. ISBN 10 consists of 10 digits, while ISBN 13 consists of 13 digits. The structure of the numbers is also different, with ISBN 10 using a single check digit at the end, and ISBN 13 using a group identifier and a country code in addition to the check digit. Additionally, ISBN 13 was introduced to accommodate the growing number of books and to align with the EAN-13 barcode system. **

Amazon provides both the ISBN-10 and ISBN-13 for books to accommodate a wider range of users and systems that may require either format for identification purposes. The ISBN-13 is the newer and more globally recognized standard, while the ISBN-10 is still commonly used in certain regions or systems. Thalia may only display the regular ISBN because it may cater to a specific market or audience that primarily uses that format for book identification. **

The registrant element identifies the specific publisher or imprint. The publication element identifies the specific edition or format of the book.

The six-digit ISBN consists of a group identifier, publisher code, and item number, and was used to uniquely identify books for cataloging and inventory purposes. **
