Definition

The ISBN of the print version of your book, that partners who sell print books can use to link print product page to ebook product page.
--> Strongly recommended.

Best Practice

In Excel, use column C "Related ISBN".
In ONIX, RelationCode 06 equals "alternative format", you can also use Relation code 13 for specific "Epublication based on (print product)"
For example, and according to the correct format code from list 150:

  • ProductIDType 15=ISBN-13.
  • ProductForm BB=Book.
  • ProductForm AC=Audio.

Multiple RelatedProduct could be linked to 1 title, as soon as the corresponding ISBN are different in each RelatedProduct composites.

Correct Usage (example)

Info Excel ONIX 2.1 and 3.0
Reference Name Related ISBN:9782246731412 
<RelatedProduct>
<RelationCode>06</RelationCode>
<ProductIdentifier>
<ProductIDType>15</ProductIDType>
<IDValue>9782246731412</IDValue>
</ProductIdentifier>
<ProductForm>BB</ProductForm>
</RelatedProduct>
Short Tag N/A 
<relatedproduct>
<h208>13</h208>
<productidentifier>
<b221>15</b221>
<b244>9783540261698</b244>
</productidentifier>
<b012>BB</b012>
</relatedproduct>

 

Notes

While Kobo Inc does not itself use the <RelatedProduct> composite, it is a useful and necessary tag for many of our partners who sell physical books.
