I've been trying to learn linear algebra, and I heard Hoffman and Kunze's book recommended many times. Now, luckily for me, our library system has it. I got it, and it is somewhat unlike the book I was recommended. Rather than the purple and blue cover it has on amazon, it is just a plane dark blue cover. The copyright date is 1961, and mine has 326 pages as opposed to 407. I believe mine may be the first edition, while it seems the second edition is the one most recommended. Is my book simply an alternate printing, or is it a different version? If so, is the first edition as good as the second?
