From The Hub:
Our reading challenge can be both completed and conquered. To complete the challenge, read or listen to 25 of the 80 titles before the deadline. Everyone who completes the challenge will be invited to submit a reader response (which can be text, audio, video, graphics, or some combination) to his or her favorite (or least favorite!) Best of the Best title, which we’ll publish here on The Hub. Additionally, everyone who completes the challenge will be entered into a random drawing to win our grand prize: a YALSA tote bag full of 2011 and 2012 YA lit titles! (If you’re a librarian or teacher, we’ll also toss in a couple of professional development titles.)
Before you ask: only titles read during the challenge period count towards the total, so if you've already read a ton of them, you'll need to either re-read them or read others.
PS. I really, really dislike this whole sign-in-to-access-the-YALSA-booklists thing. Aren't we librarians supposed to make information easily accessible?
