Hillary Clinton’s newest book, “Stronger Together,” which provides a policy blueprint for where she hopes to take the country if she is elected president, sold just 2,912 copies in its first week on sale, according to Nielsen BookScan.

Both Mrs. Clinton and her running mate, Senator Tim Kaine, have promoted the book on the campaign trail, but the sales figure, which tallies about 80 percent of booksellers nationwide and does not include e-books, firmly makes the book what the publishing industry would consider a flop.

First-week sales typically account for around a third of the total sold, thanks to the publicity blitzes that accompany publishers’ biggest releases. By comparison, Mrs. Clinton’s 2014 memoir, “Hard Choices,” which also fell short of expectations, sold more than 85,000 copies in its first week.

Mrs. Clinton’s more revealing 2003 memoir, “Living History,” about her years in the White House, sold about six times as many copies in its first week as “Hard Choices.”
