Tool usage guide
The ISBN Validator is a straightforward tool that checks the validity of ISBN-10 and ISBN-13 book identifiers. It verifies both the format and checksum to ensure the number is correctly structured and accurate.

How to use
Enter the ISBN-13 number, such as 978-0-306-40615-7, into the tool.
Outcome
The tool confirms the ISBN is valid, allowing the seller to add it to the system confidently.
Background
A librarian is digitizing an old catalog and encounters ISBN-10 numbers that require validation.
Problem
Manual verification of older ISBN-10 formats is slow and prone to errors.
How to use
Input the ISBN-10, like 0-306-40615-2, into the validator.
Outcome
The tool validates the ISBN-10, ensuring the digitized record is accurate and reliable.

ISBN-10 is a 10-digit format used before 2007, while ISBN-13 is a 13-digit format that replaced it for broader compatibility.
The checksum is a calculated digit that detects transcription errors; the tool verifies this calculation to ensure the ISBN is correct.
Yes, it supports validation for both formats, checking structure and checksum for each.
If invalid, double-check the number for typos or formatting issues, as the tool will indicate a mismatch or incorrect format.
