If you want to edit one of this combined author, step 1: EXACT search by Advanced Item Searching step 2: when the author is already added, use it. step 3: when the author is not added yet, add newly.

If the source website already removed the original page, you must confirm how the author CONSTANTLY, not occasionally capitalizes the name.
