There are 2,972 biographies of George Washington, but 5,796 of Abraham Lincoln.
If you’re counting books that are simply about Lincoln, it’s much higher — about 16,000. That’s enough books to stack three stories high. The Center for Education and Leadership at the National Park Service’s Ford’s Theatre complex has done just that. The staircase at the new center winds around a wide stack of Lincoln’s books that reach 34 feet high.
Two hundred biographies were published in 2009 alone — the 200th anniversary of President Lincoln’s birth.
