The 2012 World Book Night focused more on adults, with the thought being that adults need to be reminded of the joy of reading for pleasure. All books were donated - the paper used by the printers, the publishers providing the books, the authors donating their royalties, UPS donating deliveries, the bookstores and libraries providing pickup points and the volunteers giving the books out at various places. The places were not the usual locations one might expect to find a book, but places where people might want to read, such as bus and train stations, nursing homes, shelters, hospitals and even parks.
I found out about World Book Night thanks to my local bookstore, The Book Shelf in Winona, MN, and signed up to be a giver this year. As a giver I had the choice of one of 30 possible titles (the list can be found here). I also had submit a explanation of why I chose the title and where I planned to distribute the 20 copies of the book. As a YA author, I was more familiar with the YA titles, and my three choices were among those.
