A U.S. foundation will ship nearly $900,000 in supplies to build a state-of-the-art facility to preserve Ernest Hemingway’s books, letters and photos—the first major export of construction materials to Cuba since President Barack Obama loosened the trade embargo on the island.

The Boston-based Finca Vigia Foundation has been trying for years to help Cuba stop thousands of pages of documents from slowly disintegrating in the baking heat and dripping humidity of the sprawling home where the American writer lived and worked outside Havana from 1939 to 1960. Officials with Cuba’s National Cultural Heritage Council, which runs the Finca Vigia, have been enthusiastic about building a conservation laboratory but said they didn’t have the funds or supplies to do it.
