The Calling all Innovators: A Career for You series offers career advice for areas in which change is a given. Each title looks at a specific field, describing historical background, the current job picture, the variety of positions involved, and the process. Breaking the flow of the exposition are double-page spreads highlighting specific examples past and present, interviewing a practitioner, revealing "the artistic side," looking at a well-known company or professional association, and speculating on the future. The back matter includes statistics for three different types of jobs within the field. Television begins with the first image projections and radio broadcasting before looking at today's broad variety of broadcast materials and outlets. All titles emphasize the teamwork required in today's jobs. Underlying this approach is the premise that jobs, roles, and fields change over the years, and career planning should take that into account. These smoothly written titles offer solid introductions to exciting fields for middle-school students.

This series contains five volumes that provide an in-depth description of a particular technology, including books on rockets, microscopes and telescopes, and submarines. In Medical Imaging, Sherrow gives a complete history of a variety of imaging technologies, such as x-rays, ultrasound, Medical Resonance Imaging (MRI), and Computed Tomography (CT) scans. The author describes each invention from its initial conception through to modern usage, providing an excellent depiction of the way that these inventions change with time and increased understanding. Sherrow also does a good job of explaining the science behind each invention. The terminology and concepts are sophisticated, however, and this book is appropriate for only the most advanced high school students. In Television, Otfinoski describes the origins and social implications of television as well as modern advances. The technological explanations in this book are difficult to follow, leaving the reader unclear on exactly how televisions work. The history of programming is fascinating, however, particularly for readers with no memory of a time without a multitude of viewing options. The author skillfully explains the effects that television has had on viewers, but multiple typos in the text undermine the content. Each book contains many photographs that provide wonderful illustration, but diagrams explaining the science of each invention would have been welcome. Visual aids for understanding the technology would have truly enhanced each volume.-Heather Pittman.
