From the Harvard Library comes the Colonial North American Project, a remarkable collection of digitized letters, books, official documents, sermons, sheet music, and other archival materials from the seventeenth and eighteenth centuries. As the site notes, "these documents reveal a great deal about topics such as social life, education, trade, finance, politics, revolution, war, women, Native American life, slavery, science, medicine, and religion." At this time, highlights from the collection include an original manuscript of plays and poems by Mercy Otis Warren; a number of letters and public addresses penned by Harvard President, John Thornton Kirkland; and handwritten sermons by Cotton Mather. These items can currently be browsed by Date, Title, or document Creator. The Colonial North American Project also features five Essays that provide additional insight into select documents. For example, "Politics in the Early American Republic" describes the role that newspaper editor John Dennie played in promoting the early American republic. Readers can then peruse a number of letters written to Dennie during the late eighteenth century.
