Subject: [PATCH] Adding books: Implement a copy to clipboard button for when
 duplicates are found during the adding process. Useful if you wish to review
 the list of duplicates later. See #1276918 (The Popup for duplicate records
 does not have a "copy to clipboard" option that would be most useful)
