ISBN (International Standard Book Number) is a unique identifier assigned to each edition and variation (except reprintings) of a book. The allocation of ISBNs is typically managed by designated agencies in each country. Here's how ISBN allocation works for different types of publications:
1. Books:
Single Author Book:
- Each format or edition (hardcover, paperback, ebook) of a book by a single author requires a unique ISBN.
- If the book is later revised, a new edition will need a new ISBN.
Multiple Author Book:
- A book with multiple authors still requires only one ISBN, as it identifies the specific edition or format rather than the contributors.
2. Edited Books:
Single Editor:
- An edited book with a single editor will have a unique ISBN, distinct from the ISBN of the same book without editing.
Multiple Editors:
- For books with multiple editors, a single ISBN is usually sufficient for each edition, even if there are changes to the editorial team.
3. Conference Proceedings:
Single Volume:
- Conference proceedings published as a single volume generally require one ISBN.
Multiple Volumes:
- If the conference proceedings are published in multiple volumes, each volume should be assigned a unique ISBN.
4. Reports:
Single Report:
- A standalone report typically requires one ISBN.
Serial Reports:
- If reports are part of a series, a single ISBN can be assigned to the series. Individual reports within the series may not need separate ISBNs.
5. Ebooks:
- Ebook Editions:
- Each distinct ebook edition (e.g., Kindle, ePub) should have a unique ISBN.
6. Reprints:
Unchanged Reprints:
- Reprints of a book without any changes may use the same ISBN as the original edition.
Revised Editions:
- If there are changes (e.g., corrections, updates), a new edition with a new ISBN is recommended.
7. How to Obtain ISBNs:
Send mail to editor@pen2print.org
8. Important Considerations:
International Use:
- ISBNs are recognized internationally, but it's often more practical to obtain them through the national agency where the publisher is located.
Unique Identifiers:
- ISBNs provide a unique identifier for each edition, making it easier for retailers, libraries, and databases to manage and catalog books.
It's crucial to adhere to the guidelines provided by the national ISBN agency or the International ISBN Agency when obtaining and using ISBNs to ensure accurate and consistent identification of publications.
