University of Massachusetts, Amherst
The W.E.B. Du Bois Library at the University of Massachusetts holds the distinction of being the tallest library in the United States, at 26 stories high.
A couple of months after its opening in 1974, small pieces of brick started falling off the side of the building, a process known as “spalling.” The university responded initially by using bales of hay to isolate the spalling zone, later replaced by a “temporary” chain-link fence which remained until the late 1990s.
An urban legend says the spalling problems stemmed not from faulty bricks, but from the architect's failure to account for the weight of the library's books. While the university denied that, it did move 60,000 books out of the building.
