I've been relying on this dictionary for almost a decade. It's now got dog ears and yellow pages, but it's still in one piece since I Scotch-taped both flaps when I first got it. I did a lot of research and side-to-side comparisons at my local bookstores before settling on this one; it was the clearest and most complete pocket dictionary I could find based on the list of esoteric words I fed it. That was over a decade ago...I am not sure about today, but I wouldn't be surprised if the current edition of this dictionary is still top dog in the pocket dictionary league.
