Gr 7-10-By combining differing viewpoints with the steps to writing a persuasive essay (researching, outlining, drafting, and editing), The first book attempts to put critical thinking and writing in the context of a specific topic and, for the most part, it succeeds. An attractive layout, relevant color photographs, and useful appendixes (a glossary, an up-to-date bibliography, and lists of relevant organizations and sample essay topics) complement the text. Political cartoons lack the captions afforded photographs and charts. Many of the articles are abridged, but their actual content has not been altered to any large degree. More problematic are the sample essays' citations: the first essay has no footnotes or bibliography, the second essay has a three-item bibliography with no footnotes or parenthetical citations, and the third only footnotes the two direct quotations. While having the same occasional abridgment of articles, the second title lives up to its stated mission. In short articles, readers are coached to think about the author's perspectives with the help of a few questions and an "Evaluating the Author's Arguments" box. Visuals are engaging and always related to cloning, but not always to the specific viewpoint. Although there is a good scientific glossary, the occasional unfamiliar word (e.g., "draconian") is awkwardly defined in brackets using synonyms. The appendix contains basic information and the annotated lists of organizations and further reading are up-to-date and comprehensive. Schools sponsoring debates would find an audience for these introductions. Both are good general purchases, but suffer in comparison to the higher quality "Opposing Viewpoints" series (Gale).-Courtney Lewis, Wyoming Seminary College Preparatory School, Kingston, PA Copyright 2006 Reed Business Information.
