ALA has recommended drafting potential legislation relating to vandalism.[1] Staff members in libraries should be trained to enforce laws against vandalism, calling the police if an act of library book vandalism is taking place.[27] Outside of law enforcement, libraries should charge patrons the replacement cost of a damaged (or lost) item, if the identity of the perpetrator is known.[28] Restricting what patrons are allowed to bring into the library can help curb vandalism or theft.[29]
