I know the query is really all about the book and writing creds don't matter that much, but what if the agency specifically states "writing credits" in their submission guidelines? As a writer who really doesn't have many to boast of, should I just send in the query without a bio anyway?
A bio is NOT the same thing as writing credits. My bio is: Janet Reid is a fearsome shark who gnaws on writers for fun and profit. My writing credits are: zilch.
If you've had work published you list it.
If you haven't, you don't.
Under NO circumstances do you reach back to "I was published in my high school newspaper" unless you are still attending high school. Writing contests are not writing credits. Published work is the only thing that counts (and not self-pubbed either, sorry.)
And while I'm emailing you, I would like to give you a big pile of hypothetical bunny rabbits, because your blog and Query Shark are SO helpful.
I was wondering who sent these guys.
