Ploughshares Emerging Writer's Contest
If you are considering entering a contest anytime between now and April 2nd 2013, a good choice might be the Ploughshares Emerging Writer's Contest, which awards a winner in each category (poetry, fiction, and nonfiction) $1000. To enter, you cannot have published a book in any of the categories before April 15th.
The entry fee is $24.00, but this gives you a one year subscription to the magazine, so it's not such a bad deal.
