Do you automatically nominate all the books you publish for the big daddy awards (Caldecott, Newbery, etc)? Or just the ones you feel have the highest chance of winning? Or does somebody else do the nominating? Like the authors themselves? Clearly, I have no clue how those gold and silver medals get stamped on those books.
Editors don't nominate; marketing departments do. The smart ones nominate absolutely everything that could reasonably meet the criteria, so (for example) ours sends every illustrated book that is (a) illustrated by someone living in the US and (b) first published in the current year to the Caldecott committee. It's not our job to decide which of our books are or aren't fit to win the award; it's the committee's job.
I do suggest you read each award's criteria and guidelines before you ask your publisher if your book is being submitted for X or Y. You might be surprised what qualifies and what doesn't for different awards.
