Use this panel to choose which fields are used when Readerware checks for duplicates.
You might consider books with the same author and title to be duplicates. Select those columns
and when you do a duplicates search, Readerware will use those columns when matching records.
What about format? Do you consider hardcover and paperback copies of the same title to be duplicates?
If you do matching on Author and Title is fine. If not you can tell Readerware to match on Author,
Title and Format.
