Wow! This series, I have the two volume set, is the best I have ever read! (Even better than the book I used in college) This was used for my RN Refresher course recently. I was greatly impressed with the details, the study aids, drug information, etc. The amount of work it must have taken to put together such a comprehensive textbook astounds me. Yes, it is humungous, but well worth the cost and the time necessary to read it all the way through!
