I was wondering if anyone here has used an older edition textbook, as opposed to the newer edition, in some classes? Example, I have a few different books for my Pharmacology class starting in January, and the one on the booklist is almost $90, but can be bought used on Half.com for $60. It's the 3rd edition and is a 2010 edition. However, the 2006 edition is the 2nd edition, and can be bought for 0.75 cents used.
Another example is my Nutrition class. The book is a 10th edition, 2010 and new is $150. Used on Half.com is $80. However, the 9th edition which is a 2006 edition, is used on Half.com for $1.50.
And one more example: my Med Surg book is a 2010, 4th edition, and used is $50. The 2007, 3rd edition is $4.
I know SOME books should not be used with older editions because of changing information. The first book I mentioned, where I can get the older edition for 0.75 cents, is Dosage Calculations for Pharmacology class.
The Nutritional book is one I am thinking will not make a huge difference in getting the older edition, but I'm not sure.
Thoughts from fellow students?
