How companies like Amazon, Netflix, and Spotify know what "you might also like": the history, technology, business, and societal impact of online recommendation engines.

In this volume in the MIT Press's Essential Knowledge series, innovation expert Michael Schrage explains the origins, technologies, business applications, and increasing societal impact of recommendation engines, the systems that allow companies worldwide to know what products, services, and experiences "you might also like."

A young man battles the odds to rescue a lost explorer on Canada’s remote Labrador Peninsula in this “literate and exciting adventure story” (Kirkus Reviews). Radio operator James Ferguson was seriously wounded in a bombing mission during World War II. A piece of shrapnel buried in his spine, Ferguson was paralyzed, his brain damaged, and his voice silenced forever. But he never gave up fighting. For the rest of his life, Ferguson devoted himself to ham radio, tapping out messages to strangers in Canada, a passion no one in his family understood. But when he dies without ever connecting to his son, Ian, his final message will change the boy’s life forever. Beside the radio, Ian finds his father’s last transmission: a distress call received from the isolated Labrador Peninsula, where the survivor of a lost expedition still cries out for rescue. The authorities dismiss the story as impossible, so Ian must journey to Labrador himself. In the endless frozen landscape, he will risk his life to save another—and prove his father right. To research The Land God Gave to Cain, author Hammond Innes trekked across rough country, hearing the stories of the men who risked their lives to tame the exotic land. Innes was a master at weaving research, landscape, and heart-pounding action into some of the greatest thrillers of all time.

A yet heartbreakingly honest, endearing memoir of incredible weight loss by a young food blogger who battles body image issues and overcomes food addiction to find self-acceptance. All her life, Andie Mitchell had eaten lustily and mindlessly. Food was her babysitter, her best friend, her confidant, and it provided a refuge from her fractured family. But when she stepped on the scale on her twentieth birthday and it registered a shocking 268 pounds, she knew she had to change the way she thought about food and herself; that her life was at stake. It Was Me All Along takes Andie from working class Boston to the romantic streets of Rome, from morbidly obese to half her size, from seeking comfort in anything that came cream-filled and two-to-a-pack to finding balance in exquisite (but modest) bowls of handmade pasta. This story is about much more than a woman who loves food and abhors her body. It is about someone who made changes when her situation seemed too far gone and how she discovered balance in an off-kilter world. More than anything, though, it is the story of her finding beauty in acceptance and learning to love all parts of herself.
