Barack Obama is well on his way to becoming the bestselling author of the year.
It is a title previously bestowed on his wife, Michelle Obama, whose book "Becoming" rocketed to the top of the charts in 2018.
Now the former president's new memoir, "A Promised Land," is breaking records for the book's publisher, Crown, an imprint of Penguin Random House.
"A Promised Land" offers Obama's take on some of his most notable moments in office, from wrestling a global financial crisis to passing the Affordable Care Act.
The first of two volumes, this initial 768-page release is what Obama described in a September statement as "an honest accounting of my presidential campaign and my time in office, the key events and people who shaped it, my take on what I got right and the mistakes I made, and the political, economic, and cultural forces that my team and I had to confront then — and that as a nation we are grappling with still."
The publisher has yet to announce the release date of the second volume.
Hundreds of thousands of people pre-ordered "A Promised Land" ahead of Tuesday's release date.
Those pre-order sales, plus first-day sales, totaled 887,000 units "in all formats and editions in the US and Canada," Penguin Random House said on Wednesday.
The publisher said this result represented "the largest first-day sales total for any book ever published" by the company.
By comparison, Bill Clinton's "My Life" sold around 400,000 copies on its first day and George W. Bush's "Decision Points" around 220,000, with sales for each memoir currently between 3.5 million and 4 million copies.
For the United States and Canada, Crown printed 3.4 million copies of the hardcover edition.
Barnes and Noble CEO James Daunt told Publishers Weekly earlier in the year, "This will be a book of rare consequence. That it will sell as no other book has done since July 21, 2007" — when "Harry Potter and the Deathly Hallows" came out — "is immensely cheering to booksellers."
Booksellers expect that the memoir will remain a top seller throughout the holiday season.
Obama shared an eponymous playlist as a sort of companion to the book, which includes "some memorable songs from my administration," he tweeted.
