What is an ISBN Number of a Book?
An ISBN (International Standard Book Number) is a 13-digit (previously 10-digit) unique identifier assigned to each edition and variation of a book. It serves as a universal reference that helps differentiate one book from another, even if they have similar titles or authors. The ISBN system was introduced in 1970 by the International Organization for Standardization (ISO) to streamline the distribution and cataloging of books worldwide.
History of ISBN
- 1967: The concept of a standardized book number was first developed by Gordon Foster at the University of London.
- 1970: The ISBN was officially adopted as a standard (ISO 2108), initially consisting of 10 digits.
- 2007: The ISBN transitioned to a 13-digit format to align with the EAN (European Article Number) barcode system, facilitating easier scanning and international trade.
Purpose of the ISBN
The primary purpose of the ISBN is to:
- Facilitate efficient inventory management and sales tracking.
- Enable precise ordering, purchasing, and cataloging.
- Distinguish different editions, formats, and publishers of the same title.
- Assist libraries and bookstores in managing their collections.
Structure of the ISBN Number of a Book
Understanding the structure of an ISBN number is essential for interpreting its components. The 13-digit ISBN is divided into five parts, each separated by hyphens:
Example: 978-3-16-148410-0
Components of the ISBN:
1. Prefix Element (either 978 or 979):
- Indicates the book industry identifier.
- Commonly 978 or 979.
2. Registration Group Element:
- Represents the country, geographical region, or language area.
- Examples include 0 or 1 for English-speaking countries, 3 for French-speaking countries, etc.
3. Registrant Element (Publisher Code):
- Identifies the publisher or imprint.
- Length varies depending on the publisher's size.
4. Publication Element (Title Identifier):
- Unique to the specific edition or format of the book.
- Assigned by the publisher.
5. Check Digit:
- A single digit used to validate the accuracy of the ISBN.
- Calculated via a mathematical formula based on the preceding digits.
Note: The total length of the ISBN (excluding hyphens) is 13 digits.
Example Breakdown:
- 978-3-16-148410-0
- Prefix: 978
- Registration group: 3 (French-speaking countries)
- Publisher code: 16
