We recently received a new dictionary as a gift. Our old edition is the 1980 Oxford American Dictionary, so it's nice to have an updated volume with words like "google" and "blog." To be honest, though, when we want to find the meaning of a new word, we usually just google it anyway.
While we're working, we use Merriam-Webster's online dictionary, but when we're reading at home we reach for our hard copy. It's nice to have both - one for instant access and another for those times when we want to keep reading without getting sucked into the black hole of the computer. (We have a hard time looking just one thing up online.)
