1970, you ask? How could it possibly still be relevant? Hasn't a lot changed since then?
Well, yes, a lot has changed, but a lot has also stayed the same. What has stayed the same are the fundamentals of electricity. Voltage, current, resistance, capacitance, inductance, magnetism and so on still work the same way today as they did in 1970 (and they worked the same way before 1970 as well).
This is a very thorough book, taking you from basic circuits to transformers and motors. Some may say that the technology in the book is a bit obsolete. In some respects, this may be true, but much of what you see pictured can still be found in industrial settings. After going through this book, take a trip to the electrical department of your local home improvement store-you'll be surprised at how much sense things will make!
