So you’ve written your book, reviewed your material, prepped your layout and secured an exceptional cover illustration. So what’s next? At this stage, you may be eager to rush to the printers. But hold on a minute … there’s one more step! You need to secure the ISBN number for your book.
What is an ISBN number?
The ISBN is a unique numeric code assigned to each book that is published. It tells you the book’s publisher, title, format, language, edition and version. Think of it as an international system of ID numbers for all printed books across the world. Getting one is really quite simple.
Is it necessary?
Yes, for printed books at least. Libraries and book sellers use your ISBN to track purchases, sales and distribution. It also helps customers find your book.
Can I re-use an ISBN number?
No, you can't. Each version of your book requires a separate ISBN. If you change your book’s size, format, language, publisher, or text, you’ll need a new ISBN.
How do I get an ISBN number?
You can purchase an ISBN number online and some publishers also offer the ISBN number for free. However, before opting for a free ISBN number online, be sure to read the full terms and conditions regarding ownership, control and rights to distribution. In Trinidad and Tobago, you can purchase your ISBN number from NALIS. In the Caribbean, the CARICOM Regional ISBN Agency offers this service and in Trinidad and Tobago you can access it through the National Library and Information System Authority (NALIS).
