Did You Know That…? “Revised and Expanded Edition” is an uncommon compendium of knowledge that picks up where the original first edition left off . . . with surprising-but-true facts about history, science, inventions, geography, origins, art, music, and more . . . all the while presenting updated and new facts.
Did You Know That...? is now in its fourth edition, and it will undoubtedly continue to inform, astound, and entertain as it has for more than two decades.
