Did a quick search and didn't see this answered, so hopefully I'm not rehashing a regular question.

I just installed calibre and started adding some books. My book titles were exact, but the metadata download renamed one book as a different one altogether and picked the audiobook info for another instead of the print version. Since that's in the first 10 books I tried I'm very hesitant to throw my thousands at it, mostly because I won't know if any other books get completely changed until I hunt for them and can't find them. The other 8 downloaded the correct data.

What I want to know is, is there an undo command? If I ask for a metadata download and it picks an entirely different book, can I undo that or do I have to manually change every field back to the correct ones?

And if you get the wrong metadata for a book, is there any way to reject it and request the next best guess?

Thanks,
