HarperCollins, the second largest trade publisher in the U.S., has completed its acquisition of Houghton Mifflin Harcourt Books & Media.

HC, which is owned by Rupert Murdoch's News Corp, agreed to buy the HMH trade division in March for $349 million.

In a letter to employees, HC CEO Brian Murray acknowledged that "many" decisions need to be made over the coming months surrounding the acquisition. Still, he noted that he has outlined an initial, temporary organizational plan that will be kept in place until a new, permanent structure has been conceived.

Under that structure, Ed Spade, who took over as head of HMH trade following the departure of Ellen Archer last November, will report to Murray. On the editorial side, Deb Brody, v-p and publisher for HMH Adult Trade, will report to Liate Stehlik, president and publisher of the Morrow Group. Cat Onder, senior v-p and publisher of HMH Books for Young Readers, will report to Suzanne Murphy, president and publisher of HarperCollins Children’s Books.
