Scratch beneath the surface of a coffee bean, a red pepper flake, a poppy seed, a mold spore, a foxglove leaf, a magic-mushroom cap, a marijuana bud, or an apple seed, and we find a bevy of strange chemicals. We use these to greet our days (caffeine), titillate our tongues (capsaicin), recover from surgery (opioids), cure infections (penicillin), mend our hearts (digoxin), bend our minds (psilocybin), calm our nerves (CBD), and even kill our enemies (cyanide). But why do plants and fungi produce such chemicals? And how did we come to use and abuse some of them?

The essential handbook for doing historical research in the 21st century, The Princeton Guide to Historical Research provides students, scholars, and professionals with the skills they need to practice the historian's craft in the digital age, while never losing sight of the fundamental values and techniques that have defined historical scholarship for centuries.

Homer’s Iliad and Odyssey are unquestionably two of the greatest epic masterpieces in Western literature. Though more than 2,700 years old, their stories of brave heroics, capricious gods, and towering human emotions are vividly timeless. The Iliad can justly be called the world’s greatest war epic. The terrible and long-drawn-out siege of Troy remains one of the classic campaigns. The Odyssey chronicles the many trials and adventures Odysseus must pass through on his long journey home from the Trojan wars to his beloved wife.

Some 40 million miles of roadways encircle the earth, yet we tend to regard them only as infrastructure for human convenience. While roads are so ubiquitous they're practically invisible to us, wild animals experience them as entirely alien forces of death and disruption. In Crossings, environmental journalist Ben Goldfarb travels throughout the United States and around the world to investigate how roads have transformed our planet. A million animals are killed by cars each day in the US alone, but as the new science of road ecology shows, the harms of highways extend far beyond roadkill.

The most enduring feature of US history is the presence of Native Americans, yet most histories focus on Europeans and their descendants. This long practice of ignoring Indigenous history is changing, however, with a new generation of scholars insists that any full American history address the struggle, survival, and resurgence of American Indian nations. Indigenous history is essential to understanding the evolution of modern America.
