Warlord of Kor was originally published in 1963 as half of an Ace Double, selected by legendary editor Donald A. Wollheim. It is an interplanetary adventure, as humans probe the mysteries of the planet Hirlaj and the few remaining aliens who live there. Terry Carr never really shone as a writer, though he did write some remarkably thoughtful stories. However, his talents as an editor and anthologist were important and undeniable, and he brought many good writers and authors into science fiction and fantasy...

The Interesting Narrative of the Life of Olaudah Equiano, written in 1789, is the autobiography of Olaudah Equiano. It discusses his time spent in slavery, serving primarily on galleys, documents his attempts at becoming an independent man through his study of the Bible, and his eventual success in gaining his own freedom and in business thereafter. The book contains an interesting discussion of slavery in West Africa and illustrates how the experience differs from the dehumanising slavery of the Americas...

John Wesley Powell was a pioneer American explorer, ethnologist, and geologist in the 19th Century. In 1869 he set out to explore the Colorado and the Grand Canyon. He gathered nine men, four boats and food for ten months and set out from Green River, Wyoming, on May 24. Passing through dangerous rapids, the group passed down the Green River to its confluence with the Colorado River (then also known as the Grand River upriver from the junction), near present-day Moab, Utah. The expedition’s route...

Sailing adventure with storms, icebergs, shipwrecks, treasure, and the reawakening of a pirate frozen in suspended animation for nearly fifty years

Mutual Aid: A Factor of Evolution is a book by Peter Kropotkin on the subject of mutual aid, written while he was living in exile in England. It was first published by William Heinemann in London in October 1902. The individual chapters had originally been published in 1890-96 as a series of essays in the British monthly literary magazine, Nineteenth Century. Written partly in response to Social Darwinism and in particular to Thomas H. Huxley’s Nineteenth Century essay, The Struggle for Existence, Kropotkin’s book drew on his experiences in scientific expeditions in Siberia to illustrate the phenomenon of cooperation...

In this work, Kropotkin points out what he considers to be the fallacies of the economic systems of feudalism and capitalism, and how he believes they create poverty and scarcity while promoting privilege. He goes on to propose a more decentralised economic system based on mutual aid and voluntary cooperation, asserting that the tendencies for this kind of organisation already exist, both in evolution and in human society.

In 1907 Wallace wrote the short book Is Mars Habitable? to criticize the claims made by Percival Lowell that there were Martian canals built by intelligent beings. Wallace did months of research, consulted various experts, and produced his own scientific analysis of the Martian climate and atmospheric conditions. Among other things Wallace pointed out that spectroscopic analysis had shown no signs of water vapor in the Martian atmosphere, that Lowell’s analysis of Mars’ climate was seriously flawed and badly overestimated the surface temperature, and that low atmospheric pressure would make liquid water, let alone a planet girding irrigation system, impossible.

When the Inter-Planetary Corporation's (IPC) crack liner “IPV Arcturus” took off on a routine flight to Mars, it turned out to be the beginning of a unexpected and long voyage. There had been too many reports of errors in ship's flight positions from the Check Stations and brilliant physicist Dr. Percival (“Steve”) Stevens is aboard the Arcturus on a fact-finding mission to find out what's really happening, and hopefully save the honor of the brave pilots of the space-liner Arcturus from the desk-jockeys' in the Check Stations implications of imprecision - the nastiest insult you could cast at a ships pilot...

This is a sequel to The Skylark of Space. The novel concerns Richard Seaton and his allies who have encounters with aliens while fighting DuQuesne and the Fenachrone..

Justus von Liebig (1803-1873) was a German chemist who made major contributions to agricultural and biological chemistry and is known for his discovery of nitrogen as an essential plant nutrient. These letters “were written for the especial purpose of exciting the attention of governments, and an enlightened public, to the necessity of establishing Schools of Chemistry, and of promoting by every means, the study of a science so intimately connected with the arts, pursuits, and social well-being of modern civilised nations.”

This is the official report, published nearly 11 months after the first and only atomic bombings in history (to date), of a group of military physicians and engineers who accompanied the initial contingent of U.S. soldiers into the destroyed cities of Hiroshima and Nagasaki. The report presents a clinical description of the devastation, loss of life and continued suffering of the survivors that resulted from the world’s first and only atomic bombings. The appendix is an eyewitness account, contrasting...

First published in 1885, After London, or Wild England is considered to be one of the earliest instances of post-apocalyptic fiction, describing the effects of an unspecified catastrophe that dramatically changes the face of England and its population. Divided into two parts, the first depicts the fall of civilization, as society reverts to its more primitive roots, while the second part is set years after the apocalyptic event and examines the evident changes in both natural scenery and social structure...

The Book of the Damned was the first published nonfiction work of the author Charles Fort (first edition 1919). Dealing with various types of anomalous phenomena including UFOs, strange falls of both organic and inorganic materials from the sky, odd weather patterns, the possible existence of creatures generally held to be mythological, disappearances of people under strange circumstances, and many other phenomena, the book is historically considered to be the first written in the specific field of anomalistics. –

Arabella Buckley had a great love of nature and wished to impart that love to children. Birds of the Air will encourage children to observe birds in their natural environment and notice the habits of each particular bird they encounter.

Wild Life in Woods and Fields by Arabella B. Buckley is a collection of stories that will encourage children to become little naturalists and explore the majesty of the great outdoors. This is science taught in such a charming, delightful way that children will learn without even realizing it!

In By Pond and River, another of Arabella Buckley’s wonderful science books for children, she explains the habitats of ponds and rivers, exposing children to the animals and plant life that are found there.

In 1877, two gentlemen, Messrs Tonnison and Berreggnog, head into Ireland to spend a week fishing in the village of Kraighten. While there, they discover in the ruins of a very curious house a diary of the man who had once owned it. Its torn pages seem to hint at an evil beyond anything that existed on this side of the curtains of impossibility. This is a classic novel that worked to slowly bridge the gap between the British fantastic and supernatural authors of the later 19th century and modern horror fiction. Classic American horror writer H. P. Lovecraft lists this and other works by Hodgson among his greatest influences.

The Masters had ruled all space with an unconquerable iron fist. But the Masters were gone. And this new, young race who came now to take their place–could they hope to defeat the ancient Enemy of All?

In contrast to Scott’s South Pole expedition, Amundsen’s expedition benefited from good equipment, appropriate clothing, and a fundamentally different primary task (Amundsen did no surveying on his route south and is known to have taken only two photographs) Amundsen had a better understanding of dogs and their handling, and he used of skis more effectively. He pioneered an entirely new route to the Pole and they returned. In Amundsen’s own words: “Victory awaits him who has everything in order — luck, people call it...

Probably no other American writer has a greater sympathy with, and a keener enjoyment of, country life in all its phases—farming, camping, fishing, walking—than has John Burroughs. His books are redolent of the soil, and have such "freshness and primal sweetness," that we need not be told that the pleasure he gets from his walks and excursions is by no means over when he steps inside his doors again. As he tells us on more than one occasion, he finds he can get much more out of his outdoor experiences by thinking them over, and writing them out afterwards...
