When I was about 10 years old I got a set of World Book encyclopedias for my birthday. They got me through a lot of school projects. Unfortunately, thanks to the internet, encyclopedias are going the way of the dinosaur. The internet provides more timely information quicker. And now collaborative efforts like Wikipedia are driving another nail in the coffin.
My encyclopedias still look really nice on the shelf in the den, but they don’t see a lot of use anymore.
