While Bob Mecoy's interests are "all over the map," there are several key categories he's looking to expand, according to Rachel Kramer Bussel: Graphic novels, sports, and science. Mecoy is eager for scientific works that speak to the general public. "One of the things I would kill for is writers who can write popular science as narrative. I wish I saw more people making that more accessible, in the same way history and adventure have become accessible to a large market." What not to pitch: Romance, chick lit, history, cookbooks.
