I am getting this error when trying to add a title 'A title under this ISBN already exists on your account. Please supply a LibID if you wish to update.'

This warning will populate when you are trying to add an ISBN to your account that is already existed - if you can't see that on your account, it may be one that you have deleted from your account.

If you create a support ticket or email our team with the ISBN you wish to recover and we can arrange that with our IT team
