American Treasures Exhibition at the Library of Congress

"The American Treasures of the Library of Congress exhibition is an unprecedented permanent exhibition of the rarest, most interesting or significant items relating to America’s past, drawn from every corner of the world’s largest library. On display in the Jefferson Building Treasures Gallery in Washington, D.C., the American Treasures exhibition presents more than 250 items arranged in the manner of Thomas Jefferson’s own library, the seed from which the present collections grew: Memory (History); Reason (Philosophy, including Law, Science and Geography); and Imagination (Fine Arts, including Architecture, Music, Literature and Sports)."

In this online exhibition the Library of Congress has several items of relevance  to Ohio and the Great Lakes' history. 

A few of these include:

Map of the country about the Mississippi; Chergeree; 1755?

• Indian Map of Ohio River Country, 1755?
• "According to marginal notations, this rough sketch map was drawn by “Chegeree (the Indian) who says he has travell’d through the country.” One of the very few examples in the Library’s collection of a map drawn by a Native American, it shows Indian settlements in the area from Lake Erie to the mouth of the Ohio river in the middle of the eighteenth century."
• Jefferson's Only Published Map
• "prepared by Thomas Jefferson as a fold-out illustration for his sole book-length publication, Notes on the State of Virginia. His keen interest in geography and natural history led Jefferson to prepare the geographical text as a response to a series of questions proposed by the secretary to the French Legation in Philadelphia. This text was eventually expanded, revised, and published in various French and English editions, beginning in 1785. Jefferson incorporated his own observations, as well as those of friends and colleagues in the compilation of the map, but the final product was based primarily on existing maps, including the 1751 map prepared by his father Peter Jefferson and Joshua Fry."
• Mound Builders of Ohio
• "This Plan of the Ancient Works at Marietta, Ohio, was sketched in 1837 by Charles Whittlesey, geologist, engineer, and student of ancient North American cultures. It depicts a huge earthwork shaped by... prehistoric Indians who lived in the Ohio Valley. Such mounds, varying greatly in size and built for purposes that are still not fully understood, once numbered in the thousands throughout the Midwest. Many have been eradicated by the spread of settlement and and the expansion of farmland."
• Bartram's Travels
• "Pioneer naturalist William Bartram discovered many new species of native plants and birds during his trip through the southeastern wilderness from 1773-1777. With an artful balance of science and poetry, Bartram described the profusion of natural beauty he encountered in his Travels. Believing that civilized man could learn much from studying the Native Americans' relationship to nature, he carefully recorded details about Indian history, religion, and customs that revealed the complexity of their culture and innate virtues."
