Re Guy Fawkes' post: one of the agents who wanted to see my entire manuscript specified 'no simultaneous submissions,' but also added that if it was out with anyone I should specify with who and since when.
Anybody got an idea why an agent would want/need this information?
Assuming the other submissions were to different agencies, I don't see why the question would be asked. The agent knows others are interested, so he's aware that if he doesn't want to be scooped, he should give it priority. I'd be inclined to assure him that no-one else at his agency has the manuscript and leave it at that.
What do you think?
I think it's so they know who they're up against. For example if you had a full out with a high powered agent, a not-as-high-powered agent might put you as a priority in the hope to "scoop" the other agent. (This is a good thing. It'll get you read faster. And perhaps lead to a quicker offer that you can parlay to get high powered agent into bumping you up in their queue if they don't want to lose you to the other agent.)
Another reason if you had a MS out with Agent Y, and Agent X is good friends with them, they may pass because they don't want to step on Agent Y's toes. (This is not so good, because Agent Y might pass on it whereas Agent X might have offered. Although, if they've got similar tastes, it might have been two rejections anyway.)
Of course, the former situation I see happening more than the latter.
Alternatively, if you've got a MS out with Marginal/Scammer Agent, GoodAgent might give you a warning nod to be careful.
I think it's a good thing to tell them who has it. IMHO it puts a bit of fire under their feet to know the competition.
Good Luck!
