"Most of (the awards organizations) require the book be entered in the year it was published, and many of them have deadlines which have passed for books published in 2012. There are, however a couple that have a wider publishing window -- for example, one of them, Moonbeam, I think, allowed books published in 2010, 2011, and 2012 to be entered in the 2012 awards.
"There are also substantial fees involved, so you must decide which contests to enter based on your own marketing budget.
