The challenge will run from January to December 2011, and you can join at anytime! The rules are simple, and you can see them by clicking here.
I am participating at the Library Lust level. In order to complete this challenge, I need to borrow, read, and return 48 books between January 1st 2011, and December 31st 2011. This seems achievable to me, since books I borrow to read to my son definitely count towards this goal!
Now I just have to go to the library website, and check out my history so far this year. I am probably already near the goal since I do read a lot of library books. (I love supporting my local library, but borrowing so many books from the library means that my own books sit on Mt. TBR for too long! )
