Are you trying to add an ISBN that had already been uploaded at some point in the past - e.g. in IPR License, possibly with another account?
Important: You can use a specific ISBN/title identifier only once. Please double check if you have already uploaded this title (to a different account) before.
You may have set this title to Offline, so just go to My Books,
make any neccessary changes and set it to Live.
Also, please make sure that -
1. You have included all mandatory information for your title/s:
- Title Name
- ISBN13 (The Primary Identifier)
2. You have downloaded the most recent version of the spreadsheet from the Bulk Upload Titles page in the Manage Titles section of your account. We often make changes to this document which may mean previous versions of the spreadsheet will fail on upload.
3. You have not made any changes to the spreadsheet columns, headings, or formatting, as changes to this spreadsheet may result in a failed upload.
Please also have a look at the steps outlined on the Bulk Upload Titles page in the section Titles of your account.
If the status on the Upload History says "Completed with warnings" or "Failed", please navigate to your messages and then Admin messages and view the message related to your most recent upload. It will tell you in detail, what is wrong with the spreadsheet you attempted to upload.
