Editorial Reviews

VOYA - Lauri J. Vaughan
The four Current Controversy titles reviewed here feature between twenty and thirty-two brief opinion essays previously published elsewhere. The essays are evenly sorted among chapters that focus on specific questions. The table of contents includes a helpful abstract of each opinion. The first page of each article features a brief identification of the author—whether an individual or a foundation—and a footnote indicating its original publication. Every title includes an unauthored introduction and each chapter is briefly prefaced. Titles conclude with bibliographies and indices. As a whole, the books are attractive and readily accessible to teens. The absence of images is not a drawback as the pages are made subtly attractive with their italicized and colorful pull quotes, section headings, and rule lines. The liberal use of white space and a medium size font keep the content easy on the eyes. The weaknesses of the series, unfortunately, are plenty. The expertise of the authors is uneven and the explanations about them suspect. One wonders who wrote the text identifying TendersInfo News, the author of "E-book Pricing Should Be Decided by E-book Publishers." The explanation describes TendersInfo as a "leading business opportunity platform and information services company, providing the latest up-to-date information." Not only does this tag line sound like it came straight from a press release, the author line "TendersInfo News" is misleading. TendersInfo is a company, not a publication. Other identifiers are equally weak. Hassan Javid, author of "Although Weak, Some Secular Groups in Pakistan Are Fighting Religious Extremism," is identified as "a reporter who writes about Pakistan." Other weaknesses include unnecessarily outdated elements such as the introduction of Global Warming which predicts the "Kyoto Protocol is set to expire at the end of 2012." More problematic is the categorization of essays. To balance out the negative stance of the chapter entitled "Is Pakistan's Nuclear Arsenal Secure?" is an article about the country's energy crisis. Related? Yes. On topic? No. Beginning researchers doing superficial work will be satisfied, although they will do better if these sources are served up with an information literacy lesson on self-publishing, authority, audience and context. Serious debaters will see the flaws and look elsewhere. Subscribers to Gale's Opposing Viewpoints database will want to pass completely. (Current Controversies) Reviewer: Lauri J. Vaughan
