Artybloke, absolutely. Another thing new writers should watch out for is phony "agents" that send letters saying how they've heard about your work and want to represent you. Legit agents don't hunt down people who don't have an established, proven publishing track record, and even then I don't know of many particular cases except by recommendation of another writer or editor; how could they hear of a new author's work? It's actually much easier to get in with a trad publisher than it is to secure a talented agent. When they ask for cash up front or make unreasonable charges or they also happen to offer book doctoring services, it's time to turn and run the other way. A legit agent makes cash selling your work, not reading it.
But since it's actually easier to find a trad publisher, the key to getting one is to know precisely what that publisher publishes and from what angle (two companies may publish political works, but one could be conservative while the other is liberal), and submit it the way acquisitions wants it submitted. Follow all customary submissions rules (white 20-lb. business paper, include self-addressed, stamped envelope, clean copy, proper formatting, etc.). Have a basic business plan. Be able to tell precisely who this book will reach, why it is important, what need it will meet in the market, why it is unique (very, very important) and why this publisher is the perfect one to publish it and why you're the perfect one to write it.
While we're on the topic, here is a link called Preditors and Editors. Anyone researching a publisher might want to look at this. There are other useful features here as well:
