As itimpi said, the first selected has priority. It will keep single valued fields from the first selected record (author, title, dates, publisher, etc) and merge together multi-valued fields (tags, comments, etc.) while removing any duplicates from those fields. If a single valued field is "empty" it will fill from the second record, and then from the third record, until it finds a non-empty content for that field.
