Ford's Theater's Center for Education and Leadership sports a 6,800 volume, 34-foot-tall tower of (aluminum replica) books about Abraham Lincoln.
The majority of the titles are histories and biographies about Abraham Lincoln. Also included are books of Lincoln’s speeches, books of quotations or quips and one or two travel titles (i.e.: Indiana’s Lincolnland by Mike Capps and Jane Ammenson). Several children’s titles also are included, though not much in the way of adult historical fiction.
(Many sites report that there are 15,000 books in the pile, but that's not correct).
