Sorry if this is in the wrong forum.

I was looking at the submission guidelines for the Chicago Review Press for my novel. This is the first time I'm looking into this versus seeking an agent and I don't want to make a terrible mistake. It says it's "a good idea" to email a brief query to their acquisition editors before sending a proposal. But then down farther it has a list of what to send for a fiction proposal. So would the query letter for a publisher basically be the same as the query letter I've sent to agents? And if I don't hear back in a couple months then I can assume I shouldn't bother sending the proposal? I guess it's just to save them time from proposals they aren't interested in, but then why list the guidelines right there? This is all new to me.

Thanks!
