Hi Vijaya—we are mostly talking about something published in book form for children=best, Steve
From the description of who is eligible though, I would not qualify because I am published. However, I know in the past that in some contests there is a distinction between traditionally published, self- published, and published via work-for-hire.
I wanted to know that when you say published, do you mean all manner of making your work public?
So it's pretty clear that all published book authors are not eligible. Really nice to have an award for up-and-coming new voices that aren't repped very much in the US.
