Genres are listed in the sidebar under 2012
Nominations by Genre — just click on the category for the latest list
of nominated titles. Titles are added continuously until October 15th,
when public nominations close, and eligible publisher-nominated titles
will be added after that.
Here's the form again.
It'll be kicked back to you if you try to nominate more than one book
per genre, or if the book's already been nominated by someone else.
