Same agent for both fiction and non-fiction, at least for now, seems to be working out great.

As for finding an agent...do your homework first. Pick up the Literary Agent Market Guidebook, or the Writers Market (which has a section on agents.) Do online searches to see who is accepting new clients....and who reps books like those you write (or want to write.)

Then develop a crisp, clean, professional proposal to wow the agent! Make sure you send them what they ask for. Every good agent will have a web site. Check out my agent's web site at: www.stevelaube.com

Onward!
