I have a bit of a problem with Campbell. Like Pearson, Campbell prints texts and then changes the edition every year in order to keep selling books at inflated, publishers' prices instead of allowing students the chance to turn in used copies. Talk about a oligopoly system. Used copies lose value after a year (or a semester) depending on when Pearson decides to switch editions. One professor specifically stated that the only changes Campbell makes within the different editions are the photographs.
Do yourself a favor and purchase an older edition, and the online lab key separately. The book is also not great in terms of provided information. I'm a pre-med student nearing graduation. I found this book to be about as basic as most beginning high school biology books. Make SURE you attend lectures if your assigned this book you'll be missing a crucial abundance otherwise.
On another note, since I noticed a couple of people found this review non-helpful, biology texts are virtually unchanging. Yes, data sets and new research are continually changing and new information available, but for the most part, these basic level books don't change by much given the solid nature of the basic sciences. Where higher sciences are concerned, I select the newer text editions. Where basics are concerned, the information hasn't changed in hundreds of years (ex.Mendel's Laws, Germ Theory, Redox etc.). We are taught that we should ALWAYS question science, and anything we are learning, but in that same regard, shouldn't we also question a slimming wallet/pocketbook?
Fellow Students: Do yourself one more favor! If you're going to buy a NEW textbook, buy it from AMAZON and get a Prime account. It is WELL worth the money.
