  Definitions of Oceania vary. The broadest definition encompasses the many islands between mainland Asia and the Americas. The island nation of Australia is the only piece of land in the area which is large enough to typically be considered a continent. The culture of the people who lived on these islands was often distinct from that of Asia and pre-Columbian America. Before Europeans arrived in the area, the sea shielded Australia and south central Pacific islands from cultural influences that spread through large continental landmasses and adjacent islands. The islands of the Malay Archipelago, north of Australia, mainly lie on the continental shelf of Asia, and their inhabitants had more exposure to mainland Asian culture as a result of this closer proximity.
  
  The geographer Conrad Malte-Brun coined the French expression Terres océaniques (Oceanic lands) c. 1804. In 1814 another French cartographer, Adrien-Hubert Brué, coined from this expression the shorter "Océanie", which derives from the Latin word oceanus, and this from the Greek word ὠκεανός (ōkeanós), "ocean". The term Oceania is used because, unlike the other continental groupings, it is the ocean that links the parts of the region together. John Eperjesi's 2005 book The Imperialist Imaginary says that it has "been used by Western cartographers since the mid-19th century to give order to the complexities of the Pacific area."
  
  In the 19th century, many geographers divided Oceania into mostly racially based subdivisions: Australasia, Malesia (encompassing the Malay Archipelago), Melanesia, Micronesia and Polynesia. The 2011 book Maritime Adaptations of the Pacific, by Richard W. Casteel and Jean-Claude Passeron, states that, "for the purpose of anthropology, Oceania has long been a continent like Africa, Asia and America." Scottish geographer John Bartholomew wrote in 1873 that, "the New World consists of North America, and the peninsula of South America attached to it. These divisions generally themselves spoken as continents, and to them has been added another, embracing the large island of Australia and numerous others in the Ocean, under the name of Oceania. There are thus six great divisions of the earth — Europe, Asia, Africa, North America, South America and Oceania." American author Samuel Griswold Goodrich wrote in his 1854 book History of All Nations that, "geographers have agreed to consider the island world of the Pacific Ocean as a third continent, under the name Oceania." In this book, the other two continents were categorized as being the New World (the Americas) and the Old World (Afro-Eurasia). In his 1879 book Australasia, British naturalist Alfred Russel Wallace commented that, "Oceania is the word often used by continental geographers to describe the great world of islands we are now entering upon" and that "Australia forms its central and most important feature." He did not explicitly label Oceania a continent in the book, but did note that it was one of the six major divisions of the world. The Oxford Handbook of World History (2011) describes the areas encompassed in Oceania as being "afterthoughts in world history texts, lumped together and included at the end of global surveys as areas largely marginal to the main events of world history".
  
  The new terms Near Oceania and Remote Oceania were proposed in 1973 by anthropologists Roger Green and Andrew Pawley. By their definition, Near Oceania consists of New Guinea, the Bismarck Archipelago and the Solomon Islands, with the exception of the Santa Cruz Islands. They are designed to dispel the outdated categories of Melanesia, Micronesia, and Polynesia; many scholars now replace those categories with Green's terms since the early 1990s, but the old categories are still used in science, popular culture and general usage.
