The manuscript collection contains unique hand- and typewritten letters, diaries, account books, records of governments and organizations, and research notes. The collection is particularly strong in family history, agriculture, railroads, personal accounts of military conflicts, religion, emigration, government and politics, and early crafts and trades.
