Harper Perennial and Harper paperbacks publisher Carrie Kania will depart, heading to London to serve as an agent at Conville & Walsh. Her departure also sparked a reorganization at the publisher.

HarperCollins has restructured the Harper Perennial and Harper paperbacks imprints, bringing them under the umbrella of the Harper and William Morrow divisions. Harper Division publisher Jonathan Burnham now oversees Harper Perennial. William Morrow, Avon, and HarperVoyager publisher Liate Stehlik will take control of Harper paperbacks.

Here’s more about the restructure, from the internal memo: “Cal Morgan will continue in the role of Editorial Director of the Harper Perennial paperback originals, reporting to Jonathan. Additionally, Amy Baker, Senior Director of Marketing, and Erica Barmash, Marketing Manager, will remain with the Harper Perennial imprint, reporting to Jonathan. Gregory Henry, Senior Publicity Manager, Anne Tate, Senior Publicist, Peter Henningsen, Assistant Publicist, will move over to Tina Andreadis, VP/Director Publicity. Michael Signorelli, Editor, will join the Harper editorial team.”

This week HarperCollins promoted Michael McKenzie to senior publicity director at Ecco.

Harper director of publicity Tina Andreadis announced the promotion in a staff memo. The Ecco imprint publishes a varied list of big-time authors, including: Russell Banks, Anthony Bourdain, and Charles Bukowski.

Here’s an excerpt: “Over the past three years at Ecco, Michael has delivered stellar campaigns–from the incredibly successful ‘The Story of Edgar Sawtelle,’ every Joyce Carol Oates book (and there are many!), to most recently, the amazing coverage for Patti Smith‘s book, ‘Just Kids.’ In addition to the Ecco list, Michael delivers wonderful campaigns for the Harper imprint, most notably all of Michael Chabon‘s works. Michael is dedicated to his authors and consistently delivers fabulous results.”
