The In Controversy series examines the complex, controversial issues of the day by breaking them into smaller pieces. By studying a specific issue, for example the ethics of embryonic stem cell research, rather than the entire stem cell research debate, students gain a more solid and focused understanding of a topic as a whole. Each book in the series provides a clear, insightful discussion of the issues, integrating facts and a variety of contrasting opinions for a solid, balanced perspective. Personal accounts and direct quotes from academic and professional experts, advocacy groups, politicians, and others enhance the narrative. Sidebars add depth to the discussion by expanding on important ideas and events. For quick reference, a list of key facts concludes every chapter. Source notes, an annotated organizations list, bibliography, and index provide student researchers with additional tools for papers and class discussion.
