literary agent

A literary agent represents writers and their written works to publishers and film producers and assists in the sale and deal negotiation of the same. Literary agents most often represent novelists, screenwriters and major non-fiction writers. They are paid a fixed percentage (ten to twenty percent; fifteen percent is usual) of the proceeds of sales they negotiate on behalf of their clients.
