Dear Miss Snark:
I am new at this querying business and recently received a request for a partial, which I sent. As requested, I sent it by e-mail and haven't heard back yet (it's been a couple of weeks). My question: I realize that it may take a fairly long time until I do hear back, so what is the etiquette about continuing to query other agents while I wait? She did NOT ask for an exclusive on the partial. Is it a no no to continue on my quest for an agent or would I be naive to stop doing so until I receive her answer? Is it even a given that I will definitely hear back?
You can and should keep querying till you get an offer. Your query letters don't need to mention anyone is looking at a partial either; in fact it's better not to. We all assume multiple submissions these days. I'm always shocked if something isn't.
It's not a given you'll hear back, much to the everlasting shame of my side of the industry.
