What's Happening with the Elf on the Shelf?

Hi everyone, this is Olaf. I have only been at the library two days and already I have been found twice, once each day.

 

The Librarian elves have been kept busy giving out prizes and letting children fill out slips for a chance to win my book before Christmas.

 

I am going back into hiding now but don't worry about me I'll be taking a good book with me. 
Hint: I'm hiding near this book so you can read it too!
