A dictionary designed especially for students and teachers with all the words, including biographical and geographical entries, abbreviations, and contractions, in one alphabet.
I've read this cover to cover. OK, not really, but it's a fantastic reference book, and I've found myself using it often since buying a copy while in college. The copious use of example sentences within the definitions along with the inclusion of short foreign-language dictionaries set it apart. Please note, however, that this thing weighs about as much as a four-year-old child. Remember to lift with the knees.
