Authors often think an ISBN protects their work. It does not. They are separate things with separate purposes.
What an ISBN is
An ISBN (International Standard Book Number) is a 13-digit identifier for a specific edition of a book. It lets bookshops, libraries and marketplaces identify and order that edition. It says nothing about who owns the content.
- Each format normally needs its own ISBN: paperback, hardcover and eBook.
- A substantially revised edition normally needs a new one.
- In India, ISBNs are issued through the national ISBN agency. Check current eligibility and fees when you apply.
What copyright is
Copyright is a legal right in your original work. In India it arises automatically when you create the work. Registration is optional but can be useful as evidence if there is a dispute. Ask a legal professional about your situation.

Legal deposit
Indian law requires publishers to deliver copies of new books to designated public libraries under the Delivery of Books and Newspapers (Public Libraries) Act, 1954. Check the current rules for what applies to your book.
