You don’t have to travel Washington, D.C. or peruse some 838 miles of shelves to visit the Library of Congress.
Among the library’s 167 million items are rare books, photographs, historical recordings, baseball cards and even some human hair. Thousands of elements are added every day and millions of entries can be viewed online.
“It’s a treasure chest,” said Carla Hayden, the current librarian of Congress, on this week’s Make Me Smart. “It’s the ultimate in terms of a library.”
