Officials with Clinton's publisher, Simon and Schuster, insist her book has fared well amid reports of weak sales, and that it's succeeded despite a dramatically altered retail landscape since her last memoir.
The book sold roughly 100,000 copies from Tuesday when it was released through the following Saturday, according to a Simon and Schuster source.
The source added that the book, titled Hard Choices, is debuting at No 1 on the Indie Bestseller List, which reflects sales at independent bookstores, Politico reported.
Jonathan Karp, the firm's president and publisher, said in a statement that they were confident that they have a major best-seller.
