An organizational shift at Time Warner has moved the book group back into the Time Inc. division, home of TW's magazine operations. As a result of the change, TWBG president Larry Kirshbaum will now report to Richard Atkinson, Time Inc. executive v-p and CFO. Kirshbaum had reported to Don Logan, chairman of TW's media and communications group. In the TW pecking order, Atkinson reports to Ann Moore, Time Inc. CEO, while Moore reports to Logan.
