Query: 2,000 problems by Lipschutz and Lipson

There are more than a few reviewers who miss the point: this is not a primary teaching text, it is a supplement. That said, you can learn a lot about the topic by reading this book first and solving the problems.My chief concern is NOT the place that this book fills in the curriculum, rather, it is the large number of errors in the answers. I'm half way through and this book, along that dimension, has fundamentally lost my trust. Many people complain about multiple-edition books, but that probably allows the publisher to get the bugs out. Not so for this text, which is quite old.I do NOT recommend its purchase. Buy a book without the bugs.
