A Child's Book of Knowledge was a book published by the Britannica Publishing Company in New Tokyo on Baleyworld in 2757.[1] While written for children, by the Galactic Era it held more deep history than all of the Imperial scholars could pool together.

It provided information on Rome, China, Shakespeare, Hamlet, Buddha, Apollo, the Spacer Worlds, France, Christianity, Plato, Columbus, America, Einstein, the Empire of Brazil, Susan Calvin, and "everything from the limestone caves of Lascaux to the steel catacombs where Earthlings cowered in the twenty-sixth century."
