The (guesstimated) Top 10 authors with the largest amounts of books on my shelves Read more on Riffle
Howl's Moving Castle by Diana Wynne Jones
Diana Wynne Jones - I own the majority of her books and have read and loved almost all.
1 / 10
Running Out of Time by Margaret Peterson Haddix
Margaret Peterson Haddix - I started collecting her Among the Hidden series way back. More recently, I've been picking up the books in her "Missing" series, and I really liked some of her standalones like Running Out of Time and Just Ella.
2 / 10
Spindle's End by Robin McKinley
Robin McKinley - I'm still upset the Pegasus sequel is taking FOREVER, but I've loved so many of her books and still recommend them for any fantasy lover's bookshelf.
3 / 10
The Book of Three (The Chronicles of Prydain Book 1) by Lloyd Alexander
Lloyd Alexander - This is the point in the list where my brain forgets the "guesstimate" part and tries to remember how many books I have for each author. And I still don't know. Regardless, this is one of those FAMOUS children's authors I didn't get to until I was an adult. :)
4 / 10
The Keys to the Kingdom #1: Mister Monday by Garth Nix
Garth Nix - I think I only have his Keys to the Kingdom series, which would be 7, and maybe Sabriel on my shelf. But great imagination, great writing, and tons more books written if you like his work.
5 / 10
Dinotopia: Windchaser by Scott Ciencin
... - This is technically a series with multiple authors, but close enough. I turn into a bit of a collector/hoarder with books every now and then, and I loved these as a kid. So I scooped up most of the series used and added it to my growing children's collection.
6 / 10
The Secret of the Old Clock (Nancy Drew, Book 1) by Carolyn Keene
Carolyn Keene - Who is technically more than one author, but again, close enough. This is another of those children's collection add-on's, though it's been a slower process because I'm only looking for the original 1930's-40's books, not the '50's re-writes that I loved as a kid but laugh about now. ;)
7 / 10
The Boxcar Children (Boxcar Children #1) by Gertrude Chandler Warner
Gertrude Chandler Warner - In the great bookshelf purge before the move from Vegas, I gave away a lot of books I later wished I'd kept. My #1-#15 (or something) set of Boxcar Children mysteries moved with me.
8 / 10
The Invasion (Animorphs Book 1) by K.A. Applegate
K.A. Applegate - I read a ton of this series back in third grade and, again, wouldn't part with my small collection when we moved.
9 / 10
Dinosaurs Before Dark (Magic Tree House, No. 1) by Mary Pope Osborne
Mary Pope Osborne - I've only read two or three from this series, but I happened upon a whole stack at my used bookstore one day...I had lots of credit, which made them dirt cheap...and I figured they'd be a nice addition to my children's collection. Now I just need to drag some of the neighborhood kiddies to my library and force them to read. :)
