In polishing my query for a new agent, I'm wondering if too many previous publications can ever be considered a negative, especially if some of these books were published before the advent of Ipods, cell phones, personal computers, cable television, electric typewriters, fast food, soft cover originals, the bicycle, magic, and fire?
I don't think there is a yes or no answer.
I've read novels from guys who first published in the 60's, outlived their agents, and were on the scout for new representation. They had long lists of pub credits. Trouble was, they were still writing like it was the 60's so it was hard to think of where I could sell it. The writing was good..it just wasn't something I thought I could sell in 2006. If the writing had not reeked of mothballs I certainly would have considered taking it on.
