Theodore Roosevelt: 1917 and Now

Imagine that you were a fifth-grader in 1917, and that you wanted to learn about former U.S. President Theodore Roosevelt. You go to your school’s brand new set of The World Book Encyclopedia, which was first published that year, for help. As you read the article about Roosevelt, you would have learned many facts about him. However, there are things that the encyclopedia editors could not have known and presented in his biography—because those things had not happened yet!
