A work of astounding scope and originality that provides some of the first evidence of the modern theory of evolution. Wallace, a contemporary of Charles Darwin, spent nearly a decade cataloging the plant and animal species which inhabited the unique geographical area of the Malay Archipelago, and remains to this day one of the most extensive works of natural history ever written."

One of the great classics of travel literature. It is indeed good news that Oxford University Press has now made available a handsome new edition of the book... Natural scientists and anthropologists, in addition to being entertained, will find a vast store of scientific facts, many of which can no longer be observed firsthand." —Science Books and Films

The Malay Archipelago is a book by the British naturalist Alfred Russel Wallace that chronicles his scientific exploration, during the eight-year period 1854 to 1862, of the southern portion of the Malay Archipelago including Malaysia, Singapore, the islands of Indonesia, then known as the Dutch East Indies, and the island of New Guinea. It was published in two volumes in 1869, delayed by Wallace's ill health and the work needed to describe the many specimens he brought home. The book went through ten editions in the nineteenth century; it has been reprinted many times since, and has been translated into at least eight languages.

The book described each island that he visited in turn, giving a detailed account of its physical and human geography, its volcanoes, and the variety of animals and plants that he found and collected. At the same time, he describes his experiences, the difficulties of travel, and the help he received from the different peoples that he met. The preface notes that he travelled over 14,000 miles and collected 125,660 natural history specimens, mostly of insects though also thousands of molluscs, birds, mammals and reptiles.

Alfred Russel Wallace (8 January 1823–7 November 1913) was a British naturalist, explorer, geographer, anthropologist, and biologist. He is best known for independently conceiving the theory of evolution through natural selection; his paper on the subject was jointly published with some of Charles Darwin's writings in 1858.He was considered the 19th century's leading expert on the geographical distribution of animal species and is sometimes called the "father of biogeography". Wallace was one of the leading evolutionary thinkers of the 19th century and made many other contributions to the development of evolutionary theory besides being co-discoverer of natural selection. These included the concept of warning colouration in animals, and the Wallace effect, a hypothesis on how natural selection could contribute to speciation by encouraging the development of barriers against hybridisation.
