When Michael Gustafson and his wife Hilary opened Literati Bookstore at 124 E. Washington in Ann Arbor, they put out a 1930 typewriter for anyone to use. They didn't know what to expect.

Now, they've collected the random writings of customers on the typewriter and produced a book, "Notes From a Public Typewriter," published in late March.

Rehema Ellis of NBC News visits for the story behind the book.
