As of this point, every person who has submitted a manuscript to our picture book call should have received some sort of response from us now. If for some reason you didn't, please let us know so we can see what happened.
If I asked to hold onto your manuscript, then I will be contacting you in the next 10 days about editorial ideas I have, things I need from you, etc.
If your manuscript ended up being rejected, do not despair. You were in very good company. I only requested to continue looking at 8 manuscripts. I also would like to thank you for taking the time to send your work to us. Even though I wasn't able to personally respond to all of the submissions, I am still honored that you were willing to let me consider your work.
