Following some of their peers, Macmillan has formally announced the launch of their own speakers bureau representing the house’s authors, with representation already for over 100 speakers and “growing rapidly.” Participants include William Shatner, Emily Giffin, Senator Lincoln Chafee, Rick Atkinson, and investment guru Michael Lipper. The venture is run by Ellis Trevor, formerly a publicist at St. Martin’s, and was founded by Trevor and Thomas Dunne Books editor Kathleen Gilligan. There is more information at their site.
