After serving as executive VP and publisher-at-large for Random House since February, former Doubleday Broadway Group publisher Steve Rubin has resigned from the restructured conglomerate.

According to Publishers Weekly, the executive decided to move on after 25 years at the company. In February Rubin took on a new position, serving as a "new business advocate" after the company rearranged its imprints and laid-off many employees--a move that altered his old Doubleday Broadway Group position.

Here's more from the article: "In his memo about Rubin’s resignation, Random chairman Markus Dohle praised Rubin for having 'one of the most accomplished and distinguished careers in our company's history.' Dohle said that since becoming publisher-at-large Rubin has contributed to shaping Random's global strategy and helped land several promising projects, including the book to be written by former President George W. Bush."
