America has a huge problem. It faces four major challenges, on which its future depends, and it is failing to meet them. In That Used to Be Us, Thomas L. Friedman, one of our most influential columnists, and Michael Mandelbaum, one of our leading foreign policy thinkers, analyze those challenges - globalization, the revolution in information technology, the nation's chronic deficits, and its pattern of energy consumption - and spell out what we need to do now to rediscover America and rise to this moment.

"I was prime minister for three years and three days. Three years and three days of resilience. Three years and three days of changing the nation. Three years and three days for you to judge." On Wednesday 23 June 2010, with the government in turmoil, Julia Gillard asked Prime Minister Kevin Rudd for a leadership ballot. The next day, Julia Gillard became Australia's 27th prime minister, and our first female leader.

An incisive observer, writer, and participant in today's social movements, Zeynep Tufekci explains in this accessible and compelling book the nuanced trajectories of modern protests - how they form, how they operate differently from past protests, and why they have difficulty persisting in their long-term quests for change.

In December 2009, Google began customizing its search results for each user. Instead of giving you the most broadly popular result, Google now tries to predict what you are most likely to click on. According to MoveOn.org board president Eli Pariser, Google's change in policy is symptomatic of the most significant shift to take place on the Web in recent years: the rise of personalization.

In 2004, journalist Bill Bishop coined the term "the big sort". Armed with startling new demographic data, he made national news in a series of articles showing how Americans have been sorting themselves into alarmingly homogeneous communities - not by region or by state but by city and even neighborhood. Over the past three decades, we have been choosing the neighborhoods (and churches and news shows) compatible with our lifestyles and beliefs.

Eighteen years after the genocide that made Rwanda international news, yet left it all but abandoned by the West, the country has achieved a miraculous turnaround. Rising out of the complete devastation of a failed state, Rwanda has emerged on the world stage yet again - this time with a unique model for governance and economic development under the leadership of its strong and decisive president, Paul Kagame. Here, Patricia Crisafulli and Andrea Redmond look at Kagame’s leadership.

In July 2004, Barack Obama electrified the Democratic National Convention with an address that spoke to Americans across the political spectrum. Now, in The Audacity of Hope, Senator Obama calls for a different brand of politics: a politics for those weary of bitter partisanship and alienated by the "endless clash of armies" we see in Congress and on the campaign trail; a politics rooted in the faith, inclusiveness, and nobility of spirit at the heart of "our improbable experiment in democracy".

Fiorina shares the lessons she's learned from both her difficulties and triumphs. Drawing on her experience as a pioneering business and nonprofit leader, a politically active citizen, and a parent, she diagnoses the largest problem facing our country today: untapped potential. Too often American men and women are held back by systems that prevent them from working and flourishing. Too many people lose hope for themselves.

If you cut off a spider's leg, it's crippled; if you cut off its head, it dies. But if you cut off a starfish's leg it grows a new one, and the old leg can grow into an entirely new starfish. The Starfish and the Spider argues that organizations fall into two categories: "spiders", which have a rigid hierarchy, and "starfish", which rely on the power of peer relationships.

Despite the world's elation at the Arab Spring, shockingly little has changed politically in the Middle East; even frontliners Egypt and Tunisia continue to suffer repression, fixed elections, and bombings, while Syria descends into civil war. But in the midst of it all, a quieter revolution has begun to emerge, one that might ultimately do more to change the face of the region: Entrepreneurship.

As we approach the most important presidential election in America’s history, something has been lost among all of the debates, attack ads, and super- PACs - something that Americans used to hold in very high regard: THE TRUTH. The truth can no longer be something we hope for; it must be something we live. When courage prevails, cowards do not - and this book was written to ensure that’s exactly what happens.

In this collection of essays, Walter Isaacson reflects on the lessons to be learned from Benjamin Franklin, Albert Einstein, Bill Gates, Henry Kissinger, Ronald Reagan and Mikhail Gorbachev, Hillary Clinton and Bill Clinton, and various other interesting characters he has chronicled as a biographer and journalist. The people he writes about have an awesome intelligence, in most cases, but that is not the secret of their success.

Today, not only is everything digital getting faster, cheaper, and smaller at an exponential rate, we also have the Internet. When these two revolutions - one in technology and the other in communications - joined, an explosive force was unleashed that changed the very nature of innovation. And with any change, we have seen many strategic blunders and extraordinary learning curves along the way.

Democracy has been the American religion since before the Revolution - from New England town halls to the multicultural democracy of Atlantic pirate ships. But can our current political system, one that seems responsive only to the wealthiest among us and leaves most Americans feeling disengaged, voiceless, and disenfranchised, really be called democratic? And if the tools of our democracy are not working to solve the rising crises we face, how can we - average citizens - make change happen? David Graeber, one of the most influential scholars and activists of his generation, takes listeners on a journey through the idea of democracy.

In 1950, Fairfax County, Virginia, was 90 percent white, 10 percent African American, with a little more than 100 families who were "other". Currently the African American percentage of the population is about the same, but the Anglo white population is less than 50 percent, and there are families of Asian, African, Middle Eastern, and Latin American origin living all over the county. A Nation of Nations follows the lives of a few immigrants to Fairfax County over recent decades as they gradually "Americanize".
