A national study of instititions that preserve historical documents finds much of our heritage is in danger because of poor storage, poor conservation efforts, and lack of emergency planning. One of the few institutions to get any kind of a positive review in the study is the State Archives. The study says 80 percent of historical institutions have no emergency plans to protect collections. State Archivisit Ken Winn says Missouri is one of the 20 percent. The report says two-thirds of the nation’s artifact-collecting institutions have seen damage because of improper storage. Winn says Missouri’s archive collection is stable – and has the state’s only public document preservation lab in Missouri, which helps protect materials in the arrchives collection.
