It is difficult for today's students of archaeology to imagine an era when chronometric dating methods were unavailable. However, even a casual perusal of the large body of literature that arose during the first half of the twentieth century reveals a battery of clever methods used to determine the relative ages of archaeological phenomena, often with considerable precision. Stratigraphic excavation is perhaps the best known of the various relative-dating methods used by prehistorians. Although there are several techniques of using artifacts from superposed strata to measure time, these are rarely if ever differentiated. Rather, common practice is to categorize them under the heading `stratigraphic excavation'. This text distinguishes among the several techniques and argues that stratigraphic excavation tends to result in discontinuous measures of time - a point little appreciated by modern archaeologists. Although not as well known as stratigraphic excavation, two other methods of relative dating have figured important in Americanist archaeology: seriation and the use of index fossils. The latter (like stratigraphic excavation) measures time discontinuously, while the former - in various guises - measures time continuously. Perhaps no other method used in archaeology is as misunderstood as seriation, and the authors provide detailed descriptions and examples of each of its three different techniques. Each method and technique of relative dating is placed in historical perspective, with particular focus on developments in North America, an approach that allows a more complete understanding of the methods described, both in terms of analytical technique and disciplinary history. This text will appeal to all archaeologists, from graduate students to seasoned professionals, who want to learn more about the backbone of archaeological dating.

The Powers Phase Project was a multiyear archaeological program undertaken in southeastern Missouri by the University of Michigan in the late 1960s and early 1970s. The project focused on the occupation of a large Pleistocene-age terrace in the Little Black River Lowland-a large expanse of lowlying land just east of the Ozark Highland-between roughly A. D. 1250 and A. D. 1400. The largest site in the region is Powers Fort-a palisaded mound center that - ceived archaeological attention as early as the late nineteenth century. Archa- logical surveys conducted south of Powers Fort in the 1960s revealed the pr- ence of numerous smaller sites of varying size that contained artifact assemblages similar to those from the larger center. Collectively the settlement aggregation became known as the Powers phase. Test excavations indicated that at least some of the smaller sites contained burned structures and that the burning had sealed household items on the floors below the collapsed architectural e- ments. Thus there appeared to be an opportunity to examine a late prehistoric settlement system to a degree not possible previously. Not only could the s- tial relation of communities in the system be ascertained, but the fact that str- tures within the communities had burned appeared to provide a unique opp- tunity to examine such things as differences in household items between and among structures and where various activities had occurred within a house. With these ideas in mind, James B. Griffin and James E.

VJver forty years ago Gordon R. Willey (1953b:361) stated that "[t]he objectives of archeology ...are approached by the study and manipulation of three basic factors: form, space, and time. " A few years later, Albert C. Spaulding (1960b:439) repeated this thought using different words: "[AJrchaeology can be defined minimally as the study of the interrelation- ship of form, temporal locus, and spatial locus exhibited by artifacts. In other words, archaeologists are always concerned with these interrelation- ships, whatever broader interests they may have, and these interrelation- ships are the special business of archaeology. " Many of the means Americanist archaeologists use to examine formal variation in artifacts and the distribution of that variation across space and through time were formulated early in the twentieth century. The analytical tenets, or principles, underlying the various methods and techniques were formalized and axiomatized in later years such that by the 1930s they con- stituted the first formal paradigm for Americanist archaeology-a paradigm commonly termed culture history. This paradigm began with a very specific goal-to document the history of the development of prehistoric cultures in the Americas. Although it fell from favor in the 1960s, many of its central tenets were carried over to newer paradigms and thus continue to be fun- damental within Americanist archaeology. With Willey's and Spaulding's conceptions as our guide, we elsewhere reprinted (Lyman et al.

Anthropology, and by extension archaeology, has had a long-standing interest in evolution in one or several of its various guises. Pick up any lengthy treatise on humankind written in the last quarter of the nineteenth century and the chances are good that the word evolution will appear somewhere in the text. If for some reason the word itself is absent, the odds are excellent that at least the concept of change over time will have a central role in the discussion. After one of the preeminent (and often vilified) social scientists of the nineteenth century, Herbert Spencer, popularized the term in the 1850s, evolution became more or less a household word, usually being used synonymously with change, albeit change over extended periods of time. Later, through the writings of Edward Burnett Tylor, Lewis Henry Morgan, and others, the notion of evolution as it applies to stages of social and political development assumed a prominent position in anthropological disc- sions. To those with only a passing knowledge of American anthropology, it often appears that evolutionism in the early twentieth century went into a decline at the hands of Franz Boas and those of similar outlook, often termed particularists. However, it was not evolutionism that was under attack but rather comparativism- an approach that used the ethnographic present as a key to understanding how and why past peoples lived the way they did (Boas 1896).

Americanist Culture History reprints thirty-nine classic works of Americanist archaeological literature published between 1907 and 1971. The articles, in which the key concepts and analytical techniques of culture history were first defined and discussed, are reprinted, with original pagination and references, to enhance the use of this collection as a research and teaching resource. The editors also include an introduction that summarizes the rise and fall of the culture history paradigm, making this volume an excellent introduction to the field's primary literature.

This comprehensive contribution to the large part Irish and Irish-Americans played in the American Revolution covers genealogy, battles, fraternal organizations, and Irish friendship with George Washington.It is a refutation of Bancroft and Lodge by the historiographer of the American Irish Historical Society, with analysis of early Irish emigration to the colonies, the sympathies of the Irish with the Revolution, and the role played by the Irish in the Revolution. The appendix lists first officers, then non-commissioned officers of the American Army and Navy of the Revolution of Irish birth and descent.

How people make decisions in an era of too much information and fake news. Humans originally evolved in a world of few choices. Prehistoric, preindustrial, and predigital eras required fewer decisions than today's all-access, always-on world of too much information. Economists have largely discarded the idea that agents act rationally and the market follows suit. It seems that no matter how small or innocuous a decision might seem, there's almost no way to guess the effect it might have. The authors of The Importance of Small Decisions view decisions and their outcomes from a different perspective: as key elements in the evolution of culture. In this trailblazing book, they examine different kinds of decisions and map the outcomes, both short- and long-term. Drawing on this, they introduce a map of social behavior that captures the essential elements of human decision-making. The authors look at the New England Patriots' decision in 2000 to draft an underachieving college quarterback named Tom Brady; they consider Warren Buffett's investment strategy; and they chart the "dancing landscape" of a college applicant's decision-making environment. Finally, they show that decisions can be ranked according to transparency of choice and social influence. When fake news seems indistinguishable from real news and when the internet offers a cacophony of voices, they warn, we can't afford to crowdsource our decisions.
