I have never seen a paperback version....of Whitten, Davis, and Peck...There are texts I know of that come that way....and there is no reason to invest in the hard copy-paperback is just as good.....my Advanced Organic Text in Grad school was just fine.
PAPERBACK...and since I never intended to look at it again paperback was just wonderful.....we all have our likes and dislikes.,...I prefer to not work with things that have the potential to eat me....
