Okay, this is cool (and doesn't give any questions away)

I'm writing a game on 1936.  I went through the pile of books I hadn't used and pulled up on that is dead on for 1936, entitled "The Tercentenary of Harvard College."  You may not care, but the tercentenary of Harvard College was in 1936.  Lots of material here.  But that's not what this post is about.

What this post is about is that I looked at my copy and saw something indicating that it was a "Gift" to whatever library I had obtained it from.  And that library is . . . the Library of Congress.  They considered it a duplicate, according to the stamp on it.  But I have a Library of Congress book.  How cool is that?
