Is there any way to modify the plugin to read ISBN(ebook)number instaed of just the ISBNnumber? THanks in advance.
That isn't strictly a problem of this plugin. The plugin searches for an ISBN, if it finds one, it uses it. If that ISBN does not exist in the metadata source you are using, that is more a problem of the metadata source. Or that the ISBN found was (for want of a better term) a false positive.

Of course, it could be done. But, the plugin just uses regex to find the possibilities and then validates what was found. Adding more checks would complicate that search. But, it isn't something I am interested in doing. I don't use the plugin, and only made changes to fix it for calibre 5. If anyone wants to add this, please do so.
