  1. What is an ISBN?
    • An ISBN (International Standard Book Number) is a unique identifier assigned to books, enabling easy identification, organization, and tracking in the publishing industry.
  2. How is the check digit calculated?
    • The check digit of an ISBN is calculated based on a mathematical formula applied to the other parts of the ISBN. It ensures that the ISBN is valid and prevents errors in data entry or transmission.
  3. Can I use the generated ISBNs for real books?
    • Yes, the generated ISBNs can be used for educational purposes, testing, or any scenario where random ISBNs are needed. However, they should not be used for actual publications or commercial purposes. For real books, ISBNs must be obtained through official channels and registered with relevant agencies.
  4. Are the generated ISBNs guaranteed to be unique?
    • While the tool generates random ISBNs, it does not guarantee uniqueness or validity beyond the basic format requirements. For real-world use, it's important to obtain ISBNs from official sources to ensure uniqueness and compliance with industry standards.
