Carrie Kania, who oversees HarperCollins's Harper Perennial and Harper paperback programs and its It Books imprint, is decamping for the agent-ing business, having signed on to work at the London-based outfit Conville & Walsh. After the departure of Kania, whose title is v-p and publisher of It Books, Harper Perennial and Harper paperbacks, the publisher plans to reorganize its paperback program, putting the Harper Perennial and Harper paperbacks imprints under the the Harper and William Morrow divisions.

With the restructuring, Jonathan Burnham, senior v- and publisher of Harper, will oversee Perennial, with Cal Morgan maintain his current position as editorial director of the imprint. Liate Stehlik, senior v-p/publisher of the William Morrow, Avon, and HarperVoyager mass market imprints, will assume responsibility for the Harper paperbacks mass market titles and the list will be combined with the recently formed William Morrow Paperbacks imprint. Jennifer Hart, senior v-p/associate publisher, Mary Sasso, marketing coordinator, and Maggie Oberrender, marketing associate, will continue their work on the paperbacks, reporting to Stehlik.

Kania joined HC in 1999 and, before taking over the paperback units at the publisher, was associate publisher of Harper Audio, as well as associate publisher of HarperCollins. Two years ago Kania launched the pop culture-driven imprint It Books which has produced a number of bestsellers, including Justin Halpern's megahit, Sh*t My Dad Says. HC said it will make an announcement about the revised structure of It soon. Known for a strong eye for literary talent and skill witht branding, Kania was profiled in PW's 2008 series that spotlighted young talent in the industry, 50 Under 40.

Kania will leave HC at the end of August.
