Barack Obama is arguably the most book-loving American president since Theodore Roosevelt and Lincoln. Every summer and every year-end, he posts a reading list on his social media that instantly goes viral, sells hundreds of thousands of copies, and earns full-length analysis in the New York Times. Beyond political branding, these lists reflect a deep habit: during his eight years in the White House, Obama reportedly reserved about an hour every evening for reading in the private residence, according to David Axelrod. This discipline isn't anecdotal it shaped how he thinks, decides, and writes. Here are 10 books he has consistently named as essential to him.

The book Obama cites most often as foundational is Song of Solomon by Toni Morrison, Nobel laureate in 1993. He has stated repeatedly (notably to the New York Times in 2018): "When I was in my twenties, this novel taught me how to understand my own identity, my own story." Morrison follows Macon "Milkman" Dead, a young Black American who traces his family lineage between Detroit and Pennsylvania. Beloved, the 1988 Pulitzer winner, completes the Morrison work Obama returns to: a text that interrogates the memory of slavery through a story of haunting, one he has regularly given to his daughters and to his closest collaborators.

On American mythology and moral complexity, two references recur. Moby-Dick by Herman Melville (1851) is one of the few novels Obama has reread several times, by his own account: he sees in it a parable on pride, obsession, and the difficulty of governing people. Self-Reliance, the essay by Ralph Waldo Emerson (1841), embodies the other side: American individualism in its most demanding form, calling on each person to think for themselves rather than conform. Together these two texts illuminate the founding tension of the American psyche and therefore of much of Obama's political decision-making.

On leadership and history, two biographies became iconic in his circle. Team of Rivals by Doris Kearns Goodwin (2005) recounts how Lincoln appointed his own political rivals to his cabinet to govern through debate rather than flattery. Obama has named it among the three books that shaped him most and he applied its lesson by appointing Hillary Clinton Secretary of State after defeating her in the 2008 primaries. The Power Broker by Robert Caro (1974), monumental biography of Robert Moses who transformed New York for fifty years, is another presidential classic: 1,300 pages on the manufacture of local power, its tricks, its drift, and its human cost.

On contemporary fiction, Gilead by Marilynne Robinson (2004), Pulitzer winner, is probably the most singular novel on the list. An old Iowa pastor, near death, writes a long letter to his young son. That's it. But Obama was so struck by this book that in 2015, from the White House, he traveled to Iowa to interview Marilynne Robinson personally, in a conversation later published by the New York Review of Books. The reason becomes clear: the novel raises the question of transmission, grace, and forgiveness in a rural America whose moral culture Obama said he wanted to understand better.

On civil rights and justice, three essential reads. Letter from Birmingham Jail by Martin Luther King (1963) is one of the political texts Obama most often quotes: 7,000 words written from a cell that define non-violent civil disobedience and ground part of Obama's own presidential rhetoric. Just Mercy by Bryan Stevenson, founding attorney of the Equal Justice Initiative, recounts decades of fighting the death penalty and wrongful convictions in the American South. The Warmth of Other Suns by Isabel Wilkerson, Pulitzer winner for journalism, retraces the Great Migration: six million African Americans who left the South between 1915 and 1970, the major demographic transformation of 20th-century America.

Finally, among recent essays, Sapiens by Yuval Noah Harari holds a special place: Obama recommended it on ABC News in 2019 as "the broad fresco that helps us understand where humanity is heading." Harari unfolds 70,000 years of Homo sapiens history through three great revolutions cognitive, agricultural, scientific to explain our present. Obama sees in it a precious macro framework for anyone who has to make long-term decisions: a president, but also any leader or citizen trying to step out of the news cycle.

Reading these 10 books in full would take about 200 hours just Moby-Dick, Team of Rivals, and The Power Broker together exceed 3,000 pages. Very few people will read them all, yet they collectively open an almost presidential frame of thought: long horizon, moral complexity, tension between the individual and the collective. With Cobalt, you access the essence of each one in 5 to 10 minutes, in text or audio: the theses, the key passages, the connections between works. It's an excellent entry point to identify the two or three titles that truly deserve your hours Gilead probably warrants the full read, Sapiens too and to build, on the others, a general knowledge that holds up in conversation.
