Query: This Spanish Teacher won't use any other bilingual dictionary!

I have taught Spanish for 17 years and studied the language for 27. I found this dictionary in a used book store in Madrid, and have spent the last 5 years buying copies of if for my classroom. It is the most complete dictionary I've ever used, and once you get accustomed to the British English that pervades the dictionary it is very easy to use. Why this dictionary is out of print in the US is beyond me. The only problem with it is that it is so thick, the binding eventually breaks and you will need to tape it. No matter, this dictionary is worth it.
