When I was in college, I had a roommate who prepared to take the MCAT by reading a dictionary in his spare time. I've never read a general dictionary myself, but reading The New Dictionary of Cultural Literacy: What Every American Needs to Know is almost as omnivorous and probably a lot more interesting. I am a big believer in the concept of "cultural literacy"--that is, the idea that to communicate intelligently with others members of one's culture, one needs not only a shared language, but a body of shared ideas. So I read Hirsch's book to fill in gaps that I might have in my store of general knowledge. In doing so, I was gratified to see how much I already was familiar with in certain areas (mainly, the humanities and some branches of science), and I noted where the most gaps existed (Business and Economics, and Medicine and Health). It took me almost a year to make my way through this 600-page volume, reading a page or two at a time, but it was an interesting journey and one that was never boring. A lot of entries were terms I'd heard of but didn't fully understand what they were, but there were also those entries of which I'd never heard before. (For example, I had never heard of "settlement houses," which enjoyed their heyday in the late 19th and early 20th centuries.) I believe a person should never stop learning, never stop exercising one's mind. Reading The New Dictionary of Cultural Literacy was an enjoyable way to give my brain a little bit of a workout every day. (Note to those who read this review and might be tempted to read the book themselves: The edition I read was published in 2002. This wasn't a problem for most of the sections, but it meant the section on Technology was a bit dated--if you read this reference work, you might want to get a more recent edition.)
