From E-Claire, who got it from The Cheese Stands Alone:

Copy the list from the last person in the chain, delete the names of the authors you don’t have on your home library shelves and replace them with names of authors you do have. Bold the replacements.

here’s my list (with over 1000 books at home, these were just the first names that came to mind):

1. J.K. Rowling
2. William Gibson JRR Tolkien
3. Neil Gaiman Dick Francis
4. Neal Stephenson Madeleine L’Engle
5. Terry Pratchett
6. Charles Stross Elizabeth Moon
7. Rex Stout Anne McCafferey
8. Paul Di Filippo Earlene Fowler
9. Eric Garcia Terri Blackstock
10. Bruce Sterling Tom Clancy
