It eases my mind that it's not something that agents are sticklers about, because I've researched the agents I have on my list and none of them have specified anything I can find, either in their blogs, sites, or interviews they've given, that they have a preference for any format. So, *whew*.

I haven't read the book by Donald Maass, but I just downloaded it and am going to. I am definitely not above any reference material or advice, especially from someone who runs a very successful literary agency.

Thanks for the recommendation!
