Since February 13, over 4,000 people from 63 countries have signed up for the 2012 book exchange. These kind bookrophiliacs bibliophiles have also donated more than $31,000 through DonorsChoose.org/redditgifts, helping us get thousands of books into high-poverty schools. These could be the books that get them hooked. The ones they'll stay up late reading in bed, refusing to sleep until they finish the chapter. The ones they'll pull down from shelves when they're older and instantly remember how awesome it felt to get lost in a story for the first time…

Have you really not signed up yet?

Because these people have (We know. We don't believe it either.):

Amber Benson

Put Buffy aside, and Amber’s still incredible: she’s a geek who writes graphic novels. What would you send her?

Douglas Rushkoff

Author of loads of great books about media, technology, and culture, Rushkoff also dabbles in graphic novel-writing, and back in the day he developed the first electronic tarot reading software (“requires Window 3.1; 4MB RAM”).

Tim Ferriss

Tim has dedicated much more than 4 hours to support literacy education, and has helped raise hundreds of thousands of dollars for DonorsChoose.org to that end (just like reddit!). He also took your questions for an AMA last week (video forthcoming!).

Steven Berlin Johnson

Steven says that Everything Bad is Good for You, and we (mostly) agree! He’s a contributing editor at Wired, and has written seven books on science & technology. He’s sure to send you something good & nerdy.

Paul Goldberger

Pretty sure he’s our first Pulitzer Prize-winning gift exchange participant, and that he’ll be the first Pulitzer Prize winner to mail you a book! Hey r/architecture: are you guys hearing this?

Many of these authors joined us this year because they’ve found the persistent generosity of redditors inspiring. They’ve probably been reading some of the comments you’ve been posting over at DonorsChoose.org/redditgifts:

"I gave because books are awesome. Check them out."

"Getting kids to read more...through zombies? Just had to be done. Enjoy!"

"I gave because history tells us about real people doing real things. One person can make a difference!"

"Comics have changed my life. They encouraged me to use my imagination, and believe in the impossible. Hope they do the same for you."

"Greetings from the cold Finland! I hope you guys love HHGTG as much as I do. Don't panic, and always remember where your towel is."

"I gave because bacon bacon bacon bacon."

"I gave because I love the Lorax."

So if you're inspired, hit up DonorsChoose.org/redditgifts and help some kids get their grubby little hands on some new books!

And remember: once you sign up for the book exchange you’ll get a code to double any donation you make to DonorsChoose.org!
