This Possible: Plugin to check downloaded metadata vs book itself

[collin8579]

When you download metadata in bulk, it doesn't give you any option to really check it over and make sure its the proper book before you hit "Yes" apply to my library,,
So there could be times where it doesn't download the proper metadata, and while rare they are annoying,,

Is there a way, like the ISBN plugin that looks for Isbns within the book,
to search within the book for set things that are in the current metadata,
for instance if it says author is x, title is y,, and maybe some other stuff ,, it searches within the book (in bulk?) and returns if there are matches for x or y,, like the duplicate find perhaps?
This would allow a user to narrow down the possible wrong metadata downloads, so they don't have to go through every book to make sure its properly tagged,,

Thanks-
