The Birds of America
The University's complete double elephant folio set of John James Audubon's "The Birds of America", one of only 120 complete sets of all 435 plates in existence, was preserved and restored over a five-month process in 2000. In 2007, along with the five volume set of Audubon's "Ornithological Biography," the plates were digitized at high resolution and made available in one complete online collection.
