Once again; when I look at screenshot 3. I see a suggestion for tags (=see left) (which was empty = right). That's good!
But I also see that Published was filled (nov 2013) and that the plugin wants to change that to Undefined. Same is true for Identifiers; there is already an ISBN number and now the plugin wants to change it and add a Reader specific number. I only want the plugin to add tags and leave all the rest as it is. And it should be bulk not one by one.
