Q: I’ve written a picture book and I’m perusing the CWIM. Many publishers have multiple editors or
people in charge of Acquisition. How do I know whom to contact?
A: Great question. Read my article on submitting to editors here. It details in length how to find which editor to pick. http://www.writingforchildrenandteens.com/for-writers/step-six-find-an-editor/.
In short, it takes some amount of research, but it is well-worth the effort to target your submissions to a specific editor if you can. If you cannot narrow your choices down to a specific person, then locate the publisher’s guidelines online and send your submission to the contact listed there.
