In a rut?

So Many Books posted about how many books by the same author she has on her shelves. Since I have The Collection in a nice computer catalog that provides statistics, I thought I'd do the same (cut off, as with SMB, is 10 by an author):

• Catherine Aird
• Margery Allingham
• Robert Barnard
• Julian Barnes
• L. Frank Baum
• Enid Blyton
• Marion Zimmer Bradley
• Lillian Jackson Braun
• Elinor M. Brent-Dyer
• A.S. Byatt
• Alicia Craig/Charlotte MacLeod
• Amanda Cross
• Robertson Davies
• Colin Dexter
• Stephen R. Donaldson
• Antiona Fraser
• Jonathan Gash
• Elizabeth George
• Martha Grimes
• Carolyn G. Hart
• Reginald Hill
• P.D. James
• Diana Wynne Jones
• Faye Kellerman
• Katherine Kurtz
• C.S. Lewis
• Maud Hart Lovelace
• Ngiao Marsh
• Patricia Moyes
• Carol O’Connell
• Ellis Peters
• Elizabeth Peters
• Terry Pratchett
• Dorothy Sayers
• William Shakespeare
• Darren Shan
• Dorothy Simpson
• Lemony Snicket
• Rex Stout
• David Williams
• Chelsea Quinn Yarbro
  

I wonder who in the 8/9 books range will add to their oeuvre in 2006...
