Look at the link above to see a survey of authors from the persons who have allowed their libraries to be public. The size of the author name gives an indication of the number of entries. Very gratifying to see C.S. Lewis and Gene Wolfe among those listed in larger type.
In a bit of a surprise Neil Gaiman's name rivals that of J.K. Rowling and Terry Pratchett. That is gratifying as well. I don't know what's wrong or right with Gaiman, but Coraline was a creepy masterpiece.
My favorite by Gaiman was Neverwhere. Also, if you haven't read Good Omens by Neil Gaiman and Terry Pratchett you have a real treat in store. A hilarious book about the Apocalypse ... hard to imagine but they pull it off perfectly.
