I've never used an agent.
If you've received an offer from a publisher in response to your submission, then you will receive all of the money. If you receive an offer via an agent, you will receive money, minus the agents fee. (What is traditional? ___%)
It seems like 100% is better than something less. Unless, of course, the agent can get you a significantly higher price. (At least enough to pay his fee.)
Am I missing something?
I'm glad things work out well, Codger, but that may be a function of you having far more base knowledge and industry contacts than the average writer. You may not be missing anything by foregoing an agent. But I sure would be.
If you're dealing with small press, academic press, e-publisher, etc., non-agented can certainly be the way to go. There's just not as much latitude with the budget. But with larger commercial publishers, there's much bigger disparity in the kinds of deals that are cut with agented and unagented writers.
If you're well-versed in literary contract law, negotiating advances and royalties, knowing which clauses to strike, which rights to retain and how to sell them separately, that disparity can be narrowed considerably. If you have all the industry contacts to whom you can sell merchandising rights, first serial rights, audio book rights, library, book club, etc., and overseas contacts for foreign rights, then certainly the necessity of an agent diminishes.
I sure didn't/don't have that kind of knowledge.
When I was sending out my first book, I queried agents and publishers simultaneously. I received an offer from a publisher while two agents were still considering the manuscript. So my first inclination was to think yippee! I don't have to fork over 15%. The agent (that I signed with) kindly explained the facts of life. With one phone call, without even starting negotiations, the deal would sweeten, just on the basis of the publisher's knowledge I was repped. The
pro se newbie author contract would go back in the drawer and the starting point for negotiations on the advance would be considerably higher for a pre-empt. Or she could shop it. The royalty scale would be bumped up. Plus all the subsidiary sale stuff, which I wouldn't have had a clue about.
Even if I did have the knowledge and contacts to do all that, imagine the time it would take. And then there's the whole business of having to do your own cage-rattling and reminding and nudging and arbitrating during the editing/publication process. An agent's practiced eye on the royalty statements are invaluable too.
