So many thing I first learned about while flipping through this, like: Nobel Prize winners, Shakespeare plays, Dostoyevsky (described as "A Towering figure in world literature", a phrase which stuck in my head) and so on.
I even remember that "Aachen" and "Abdul-Jabbar, Kareem" were both on the very first page :D

From Columbia University. Available practically everywhere. This one-volume encyclopedia provides concise explanations of the most important events in history. It is easy to use and indispensable. Find it used somewhere at a low price.
Not as detailed as the World Book set but it still has more information than a dictionary, for the most part. A few topics were covered in only two or three lines.
