Top Authors?

You may (or may not) have noticed that we (or really, I, since Trackgeek doesn't keep tabs like I do) have switched from Shelfari to Goodreads. It was a difficult decision - I felt disloyal and I will miss it, but Goodreads is just bigger and better. For crying out loud, they send me emails when new books are being added from authors I read. And their latest? Top authors I've read.
Now, I must say, some of them it's hard to count. I mean, at one point I added something like 40 Agatha Christie books because I went through a phase in college where that was ALL I read. So, I'm going to ignore those authors whose numbers are so high because I devoted much of my childhood/high school experience to them (Carolyn Keene, anyone?). Not that that's bad, but I wanted to know currently what I seem to be reading the most. So. This list is authors that I have read in the past FOUR (4) years. If you feel that's cheating, go ahead. Yell at me. :)

So, here are the top 10, and in case you're curious, they DO count anything on your 'to read' shelf.

Ahem:

1. Patricia Wrede, with a whopping 14.
2. Lloyd Alexander, 12.
2. Eva Ibbotson, tied to Mr. Alexander with 12.
3. L. M. Montgomery, who yes was a favorite childhood author, but whose books I have continued to read as an adult, so hats off to Ms. Montgomery and her 11.
4. C. S. Lewis, 10. Of course when you remember there are already 7 in the Chronicles of Narnia...
5. Vivian Vande Velde, is a surprising 8.
5. Charles Dickens, 8.
5. Margaret Peterson Haddix, another surprising 8.
And to round out the top ten, here are all the authors that had 7 - sorry, it's a lot!
Margaret Haddix, Anthony Horowitz, J. K. Rowling, John Grisham, Robert Louis Stevenson, Robin McKinley, Sharon Shinn, Sherwood Smith, Avi, and Gail Carson Levine

And for curiosity's sake, the authors that I 'passed' in between the above listed authors:
Agatha Christie
Carolyn Keene
Laura Ingalls Wilder
Roald Dahl

I think there are a few quirks to fix - anything, for example, with Jane Austen in the title was counted towards Jane Austen. And sometimes I found doubles - perhaps I'd read two editions, but when you say you read The Hobbit, for example, you don't count it as two of Tolkien's works, just one read twice. At any rate, I thought it was a lot of fun. Anyone else have a list? Any surprises?
