Perhaps you should try some spelling variations:
"michael kirby author" » "michael kelly author", "michael derby author", "michael burnby author", "michael diary author"
"michael kirby anthony" » "michael kelly anthony", "michael kerby anthony", "michael birley anthony", "michael kirton anthony"
"michael della author" » "michael kelly author", "michael heller author", "michael de author", "michael cells author", "michael wells author"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("michael kirby author") OR ("michael kirby anthony"))) OR ("michael della author"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"michael kirby author\") OR (\"michael kirby anthony\"))) or (\"michael della author\"))*".
• Removing quotes may allow a broader search: (((( michael kirby author ) OR ( michael kirby anthony ))) or ( michael della author ))*.
