ISBN for the book

The ISBN is an international standard number for books

The ISBN is a unique 13-digit identifier assigned to each specific edition of a book—similar to a personal identification number for a person. It helps publishers, libraries, and readers accurately identify the exact work and edition in question.

If the same book is published in multiple formats - such as print, e-book (PDF or ePub), or online (readable directly on the web) - each format requires its own ISBN. This is because each version is considered a separate product, potentially with a different price, distribution method, and usage environment.

Applying for an ISBN in the Publisher Portal via the Library

ISBNs are issued for textbooks, doctoral theses, books, etc.
