As a 3rd grade bilingual teacher, Spanish/English dictionaries are a must in the classroom. This volume is more than adequate--you are certain to get your money's worth, as far as finding the exact "sense" of the word you are looking for. The only problem, is that it is quite thick for a paperback volume. It is one of those books where you hold down the excess with your opposite forearm while trying to judge the thickness of how much to turn in order to get to the desired letter with the fingers of both hands. If you have little fingers using it, it will very quickly curl up from both front and back. If you are a backpack-toting dictionary-hauler, or if you read anywhere other than at a flat surface while using your dictionary, it might be a little easier going to to Merriam Webster's--which is a bit smaller in thickness, but works quite well. I have found the New World dictionary even bulky for me--a petite adult. As far as content quality, however, there is no better buy for the money.
