These items are generally arranged either chronologically or alphabetically by composer. The biographical materials are comprised largely of performance data and incoming correspondence. Performance data, including publicity, programs, and reviews, are arranged chronologically in several subseries.
Correspondence is arranged alphabetically by name of sender.
Remaining materials, such as appointment books, photos, and financial documents, also follow a general chronological order. Subsequent subseries are of theatre organ materials and miscellaneous personal and family items. In 1915 the family, including an older sister, Rachel, returned to the United States.
