Written at a level accessible to nonspecialists, including high-school students, college students in introductory courses, and the general public, this encyclopedia's purpose is to assist users in acquiring knowledge and understanding of chemistry. The 509 alphabetically arranged, signed articles were written by subject specialists and range from concise definitions to multiple-page overviews. Broad areas covered include analytical chemistry applications, biochemistry, biographies, elements, energy, environmental chemistry, medicine, organic chemistry, physical chemistry, reactions, states of matter, and structure. Examples of specific article titles are Alchemy; Artificial sweeteners; Boron; Clones; Franklin, Rosalind; Isomerism; Mole concept; Nanochemistry; Rubber; Spectroscopy; and zwitterions. In addition to explaining scientific principles, this set relates chemistry to everyday life. For example, Silly Putty (a silicone-based material) is a "liquid solid," the color of hydrangeas is determined by soil acidity, and endorphins may allow marathoners' bodies to endure long races.

The 450 articles have been written by an impressive array of world scholars, creating an appropriately global perspective. A brief time line of politics and helpful glossary of terms are appended, along with a reader's guide and index... The work is a solid and lasting contribution to the understanding of the issues that divide us politically. Highly recommended for its readability, scholarly content, and uniqueness

Population means more than people, births, and deaths. Population studies measure how people live, the environment they live in, and the resources to support life. The 336 articles in the Encyclopedia of Population discuss topics as varied as Divorce, Immigration, Land use, and Prehistoric populations. A topical outline provides a thematic view of the encyclopedia's content, which ranges from population theory to the cultural and political aspects of population.
Each entry is 500 to 1,000 words in length, contains a bibliography, and is signed by one of 278 authors - all published scholars from around the world. Among the longer entries are Climate change and population; Diseases, infectious; and Sexuality in humans. As is expected within the field of population, many charts, tables, and graphs accompany the text, including several in an appendix. Biographical entries on 60 individuals whose work was important in the development of population studies - for example, Thomas Malthus, Karl Marx, and Margaret Sanger - are included. Finding aids include an alphabetical list of articles, see and see also references, and an extensive index.

The antitobacco litigation of the 1990s, culminating in the $206 billion Master Settlement Agreement, led to a lull during which this encyclopedia could be produced without fear of its being immediately overtaken by events. The editor has used the opportunity to good advantage. Tobacco in History and Culture contains 136 articles addressing every important aspect of the tobacco phenomenon and the controversies spawned by the revelations of the past several decades, most notably those relating to health risks and to the tobacco companies' awareness of those risks, long before the public was made aware of them. At this point, with the companies concentrating on foreign markets, this work will become outdated only in regard to the inevitable upward revisions of projected tobacco-related deaths in those markets-which include underdeveloped countries, where medical facilities are least capable of dealing with the results of tobacco use.
Entry length ranges from just over a page for Black Patch War (an early-twentieth-century conflict between Kentucky tobacco growers and the American Tobacco Company) and Opium to more than 10 pages for Disease and mortality and prohibitions. Each entry concludes with a bibliography, and numerous terms are defined in page margins. Other features of the set include 250 well-chosen and well-reproduced black-and-white illustrations and, in both volumes, a section of color plates. Sidebars contribute additional facts and perspective.
