Science- and technology-minded students will welcome this well-written, fact-filled series showcasing researchers using actual technological tools to investigate the paranormal. Easy-to-understand prose makes most of the technical language comprehensible. Some readers may find the text a bit tricky, as not all concepts are explained. However, strivers should find the series a generally comfortable read overall, with only two to four sentences per page. The volumes describe what proof tech devices have already found or continue to search for. Interestingly, in the UFO and cryptid volumes, it’s noted that “everyday technology” such as cameras and computers are also used. Current technological advances in all these investigations are cited. The series is handsomely designed, with provocative, high-quality color photos of technological wizardry, usually featuring captions. There are many photos of actual tech items, including Mars rovers, ghost-detecting gadgets, telescopes, lasers, radar screens, and sonar images. Sidebars provide additional facts. Besides glossaries, the back matter in each title includes a bibliography, a brief list of internet sites, and an index. VERDICT Recommended, especially for mature, science-/tech-minded students in school and public libraries.
