The partially enclosed section of the library’s loggia features one of the island’s largest shell collections. The Henry Francis du Pont Collection, in the two right hand cabinets, were reported to have been collected locally on Gasparilla and Little Gasparilla Islands by Henry F. DuPont and his family from 1920 until 1969. The collection was donated to the Johann Fust Community library in 1969 in his memory by his family.
