The collection consists of letters written to Arthur Barry by his sons H. Brewster Barry and H. Pomeroy Barry, other relatives, and friends. There is also correspondence with the officials of the schools the boys attended, as well as letters concerning the property Barry owned, and his financial and business affairs. The rest of the collection includes Barry's private journals, personal financial and tax records, and the reports and correspondence of the charities and clubs with which he was affiliated. The correspondence and records of the East Side Savings Bank, the Community Savings Bank, and the Rochester Trust and Safe Deposit Company make up the balance of the collection.
