The American Antiquarian Society, an independent research library, has provided a digital collection of the Grant-Burr family papers on their website. The letters in this collection were written between the years 1827-1892, and a majority of the correspondence is between Daniel Grant and his wife Caroline Burr Grant. There are over 500 letters, covering a great range of 19th century topics from courtship and childrearing to westward expansion and the Civil War. The collection can be searched by keyword or, perhaps more usefully, can be browsed according to subject. Additionally, the website offers genealogical information and images of the family. All of the transcribed letters are available as a scanned pdf file which is useful for those seeking to use these letters in the classroom. For more information on how to use primary sources in the classroom, teachers may want to refer to this page from the Library of Congress.
