If you already have your own ISBN, you have two options for displaying it on your book:
1. Blurb-placed ISBN: Our placement (bottom center of back cover) with our display (barcode, no price).
2. Custom-placed ISBN: Custom placement (wherever you want on the cover) with custom display (include price if you wish)
When you use our book-making tools and enable the option to use your own ISBN, you will automatically opt into Blurb placement of your ISBN.
If you'd like to have more control over where the barcode is placed on your cover and what information displays, you can add your ISBN and barcode as an image on your back cover. If you use your own ISBN do not select the ISBN option in the software or at upload.
Making a Trade book?
Please note that our Trade Books require a Blurb-placed ISBN. Do not include a barcode image on your Trade Book cover. If you do, the cover will display both your barcode and the Blurb-placed barcode.
Add your own ISBN as an image
Add your ISBN and barcode image to the back of your book as part of your cover design. We recommend adding the barcode as a PNG image rather than a JPG for the sharpest results.
When uploading your book with your ISBN as an image, do not select the option to use your own ISBN because this will add an additional barcode to the back of your book.
And remember, if making a Trade book, those require a Blurb-placed ISBN. Don't add your own ISBN image in that case.
