Review title: A patchwork monster
Product review: Another motley McGraw-Hill product. First copyrighted in 1913. The author appears to have died prior to 1976, and the book has been maintained by hired help. Don't try to use this as a textbook; treat it as a reference only. You never really know whether some item is up to date or 50 or 80 years old. Examples: There is a lot of treatment of two-phase (yup, 90 degrees) power, including at 25 hertz, and of multi-kilovolt series incandescent streetlighting, plus knob and tube wiring. Also, it is stated that the highest radio frequency in use is 30 megahertz, whereas in reality we're up to 1,000 or 2,000 times that just now. This book is a curiousity; charming if you have the cash, but if you don't, maybe you should be getting something more coherent.
