The John James Audubon in Louisiana collection contains water colored lithographs and engravings of birds Audubon did during a 4-month stay at the Oakley Plantation in St. Francisville, Louisiana in 1821. Many were later published in various incarnations of Birds of America. The Audubon prints chosen for digitization are in two different forms: large, loose folios (30" x 40") and octavo book plates (7" x 11") and were chosen from the "John James Audubon Collection," part of the library's E.A. McIlhenny Natural History Collection. This collection contains a complete Elephant Folio, one first-edition Royal Octavo, four later-edition Octavos, 117 separate Folio prints, and 32 original pencil drawings associated with the production of the Octavo edition of the Birds of America.
