I’ve noticed from my online research that many agents say one of the top criteria in offering representation is the author’s willingness and enthusiasm for manuscript revision. I actually enjoy the revision process, and I’d like them to know that up front. Should I mention it in my query and if so, in my bio paragraph or where? Do you have any suggestions for wording? Or should I wait and bring it up during The Call, when we each ask questions of the other in hopes of progressing to representation? Thanks for your views on this subject.
You're forgetting the one crucial place where you SHOW an agent that you're adept with revision: when the agent sends you editorial notes.
I'm much more likely to believe what I see over what I'm told.
So, how do you show you like revising?
1. You read the editorial letter carefully and ask about things you don't understand.
2. You know that the agent wants more than what she's written. That means if she says "this scene drags on too long" you understand you should analyze WHY that is, and look for other scenes it might apply to.
3. You ask about the agent's time frame. Often it's open-ended. That doesn't mean you have all the time in the world and it also doesn't mean rush. Work steadily, then allow time for the manuscript to sit, then go back.
4. Ask the agent it she wants updates, or just wants to know when it's almost ready to come back to her.
I'm always glad to have a client who can revise, but truth be told I'd rather get a manuscript in that didn't need it.
To answer your question: you don't put this in your query letter, much like you don't put how much you love canoodling in your online dating profile.
