BOOKS BY HENRY PETROSKI
THE BOOK ON THE BOOKSHELF
As writing and literacy advanced over the last two thousand years, the development of the book was seemingly inevitable. As books grew more common, the question of how to store them became more pertinent. But how did we come from sheets rolled on spools to the ubiquitous portable item you are holding in your hand? In The Book on the Bookshelf, Petroski answers these and virtually every other question we might have about books as he contemplates the history of the making and storing of books.

ENGINEERS OF DREAMS
Great Bridge Builders and the Spanning of America
In Engineers of Dreams, Petroski explores the engineering—not to mention the politics, egotism, and sheer magic—behind America’s great bridges. It is the story of the men and women who built the St. Louis, the George Washington, and the Golden Gate bridges, drawing not only on their mastery of numbers but on their gifts for self-promotion. It is an account of triumphs and ignominious disasters (including that of the Tacoma Narrows Bridge, which twisted apart in a high wind). In this engaging book, Petroski lets us see how bridges became the “symbols and souls” of our civilization, as well as testaments to their builders’ vision, ingenuity, and perseverance.

THE EVOLUTION OF USEFUL THINGS
How did the fork acquire a fourth tine? What advantage does the Phillips-head screw have over its single-grooved predecessor? Why does the paper clip look the way it does? What makes Scotch tape Scotch? In this delightful book, “the poet laureate of technology” takes a microscopic look at artifacts that most of us count on but rarely contemplate. At the same time, he offers a convincing new theory of technological innovation as a response to the perceived failures of existing products—suggesting that irritation, and not necessity, is the mother of invention.

PAPERBOY
Confessions of a Future Engineer
As Henry Petroski recounts his youth in 1950s Queens, New York—a borough of handball games and inexplicably numbered streets—he winningly shows how his after-school job amounted to a prep course in practical engineering. Petroksi’s paper was The Long Island Press, whose headlines ran to COP SAVES OLD WOMAN FROM THUG and DiMAG SAYS BUMS CAN’T WIN SERIES. Folding it into a tube suitable for throwing was an exercise in post-Euclidean geometry. Maintaining a Schwinn revealed volumes about mechanics. Reading Paperboy, we also learn about the hazing rituals of its namesakes, the aesthetics of kitchen appliances, and the delicate art of penny-pitching.

PUSHING THE LIMITS
New Adventures in Engineering
Pushing the Limits celebrates some of the largest things we have created and provides a startling new vision of engineering’s past, its present, and its future. It highlights our greatest successes, like London’s Tower Bridge; our most ambitious projects, like China’s Three Gorges Dam; our most embarrassing moments, like the wobbly Millennium Bridge in London; and our greatest failures, like the collapse of the twin towers on September 11. Throughout, Petroski provides fascinating insights into the world of technology with his trademark erudition and enthusiasm for the subject.

REMAKING THE WORLD
Adventures in Engineering
Feats of engineering have changed our environment in countless ways, big and small. Remaking the World focuses on the big: the Panama Canal, a cut through the continental divide that required the excavation of 311 million cubic yards of earth. It tells the stories of the personalities behind the wonders, from the jaunty Isambard Kingdom Brunel, designer of nineteenth-century transatlantic steamships, to Charles Steinmetz, genius of the General Electric Company, whose office of preference was a twelve-foot canoe. This spirited book is a celebration of the creative instinct and of the engineers whose inspirations have immeasurably improved our world.

SMALL THINGS CONSIDERED
Why There is No Perfect Design
Why has the durable paper shopping bag been largely replaced by its flimsy plastic counterpart? What circuitous chain of improvements led to such innovations as the automobile cup holder and the swiveling vegetable peeler? Henry Petroski looks at some of our most familiar objects and reveals that they are, in fact, works in progress. For there can never be an end to the quest for the perfect design.

THE TOOTHPICK
Technology and Culture
From ancient Rome, where emperor Nero made his entrance into a banquet hall with a silver toothpick in his mouth, to nineteenth-century Boston, where Charles Forster, the father of the American wooden toothpick industry, ensured toothpicks appeared in every restaurant, the toothpick has been an omnipresent yet often overlooked part of our daily lives. Here, with an engineer’s eye for detail and a poet’s flair for language, Henry Petroski takes us on an incredible tour of his most interesting invention. Along the way, he peers inside today’s surprisingly secretive toothpick-manufacturing industry, and explores a treasure trove of the toothpick’s unintended uses and perils, from sandwiches to martinis and beyond.
