For a non-math person, this is one of the easiest to read texts on modern algebra. However, I cannot find an errata for it.  Like any text, there will be errors. (I am writing this review just 3 pages from the end, but was stuck on the proof of theorem 4 in chapter 33 because it was incorrect.... Fortunately, other proofs available on the web show the error... Wish I didn't waste so much time scratching my head just as I was nearing the end!)
