I bought the Kindle edition of this book and immediately returned it. There is no way to readily go to
the monograph on a particular drug. You can do a painfully slow search and bring up every instance where that drug appears in the book but you can't just, for instance, go to the "C's" and bring up "Codeine." The index is there but no page numbers. Totally unusable. I went to Skyscape, a seller I am not particularly fond of, and paid $20 more, but have a totally usable product. I found this same concern with "Williams Obstetrics" for Kindle but kept it because I got a good price and being able to bring up a subject very rapidly is not as much of a concern.
