An agent recently tweeted that she wanted people to mention in their query letter if they had submitted past projects to her. Now, if someone had requested a full from me before I could see the benefit to this, but what about someone who declined to request material or didn't even respond? Should we remind even the rejections that they've seen our names before?
I'm going to take a wild guess here and mean "submitted past projects" means submitted full manuscripts, not queries.
I'm not sure why anyone wants to know this, but if she does, she does. On the other hand if it's not in her submission guidelines, how the hell is anyone to know unless they happen to see that particular tweet?
And truly, honest to god, this is just one more way to make writers crazy. I'm of a mind that making it as easy and straightforward to query the better. Time enough to make your clients crazy when you need a synopsis for a film deal in 30 minutes.
