Why do so many keep singing praises for a book that need a companion volume of errata? Just put the thing into the toilet and do a big sloppy #2 on it.
I am disappointed with the qualify of PEfI, 3rd and think there are too many errors. Some are inexcusable, particularly for the 3rd edition. If you have a local library, check for electronics books -- mine has AoE 2nd edition and others. Or find a used copy of a better book.
Having recently bought this book, before stumbling upon this thread, and I tend to agree. I don't understand the praise it's garnering. I chose it due to its high rating on Amazon, but having actually read it... I find it at times confusing, sometimes contradictory, often outdated (for example, half the time it correctly refers to 120V mains in North America, at others it refers to 117V mains, which hasn't been the nominal voltage for decades), but most of all, I don't really quite understand why some topics are started in one place, then finished in another. When I read it cover-to-cover, several times I found myself puzzled at encountering a topic again, with different information than in the first mention.
Is it full of useful information? Yes, no doubt. But the technical writer in me (I did that for a few years) thinks it needs a LOT of editing to become a truly good book.
I also think this book is just begging for a better binding than paperback. It's kinda crazy that this is paperback, yet the local electronics distributor (Distrelec) sends a free catalog that is hardcover, 2600 pages in full color!
Now, off to compare the errata to my copy. (7 8 9 0 QVS/QVS 10 9 8 7 6 5 for those who were wondering.)
