I’d honestly be fine with looking at perfect replicas, so it’s not a big loss when accidents happen.
At the Richard Nixon Presidential Library, where I work as a volunteer docent, we have Nixon's parents' copy of The White House Cook Book (1887), However, we have on display another copy that the Nixons didn't own and keep the original locked away so as to protect it from light damage and other hazards. The original is brought out only on special occasions.
