When publishing books from Contribute users must have sufficient permissions to the objects and folders. If you don't have sufficient permissions to a book, a message appears when you try to publish.
To enable publishing from Contribute, make sure you have at least Read permissions for the objects used in the book.
If a book fails to publish, check the publishing log as it lists any objects you do not have permissions to. If you do not have sufficient permissions, discuss your options with your Library's Security Administrator.
