It was a day of unexpected absences at the Rogers Cup on Tuesday: Andrea Petkovic failed to make her match, Svetlana Kuznetsova pulled out injured, the power went out, and so too did an inconsistent Eugenie Bouchard.

For years, librarians at a small central Illinois library gossiped that a tattered book lying on one of its shelves justifying racism may have been in the hands of none other than Abraham Lincoln, the Great Emancipator.

On Tuesday, state historians confirmed that theory by announcing Lincoln's handwriting had been found inside the cover of the 700-page text, at the same time taking great pains to offer reassurance that the former president who ended slavery in the U.S. didn't subscribe to the theories at hand, but likely read the book to better educate himself about his opponents' line of thinking.
