The campaign goes into high gear when the book appears June 22 in a one-day laydown nationwide. The week kicks off with a “60 Minutes” interview, followed by appearances on “Oprah,” the “Today” show, “Larry King” and “Charlie Rose.” To accommodate demand beyond the 2.3 million copies ordered by retailers, Knopf has already reserved press time at the printer’s and stockpiled paper for subsequent editions. The real trick, of course, will be keeping the book under wraps until the publication date. In the absence of a new “Harry Potter” this year, Clinton’s book is the hands-down favorite to be The Book Most Likely to Appear Before Publication on eBay, where posters for it are already being offered for $4.99.
