The high priest in his robes. Exod. xxviii. 39 / lith'y. of A. Kollner Philadelphia ; H. Camp's lith'c. press.

The invention of lithography at the turn of the 19th century opened a new world for bird illustrators. It brought many advantages to the artist — ease of use, a softness of line, and a new freedom to effect bold designs with a wide range of light and dark tones. Most of the fine ornithology books of the 19th century were prepared in folio format with hand-colored lithographic plates. The lithographic process is one of flat surface printing from a design drawn on stone. It is based on the principle of the resistance of grease to water. There are no raised or cut portions, as there are in engraving and etching. The image is drawn with greasy ink or chalk on a smooth stone, and the rest of the stone is treated with gum arabic and nitric acid. The gum retains the lines of the greasy design, which repels the water used in printing. Special paper and ink, as well as a special press, are needed to produce the prints. First used for bird illustration in 1820, lithography was widely adopted by the best artists of the century. The technique was popular because the artist could draw his own illustration directly on the lithographic stone. Prints could be made from the drawing with no intermediary such as an engraver. Accurately reproduced and then colored by hand, the resulting illustrations gave the impression of original watercolor paintings.

The Americana collection of Marian Sadtler Carson (1905-2004) spans the years 1656-1995 with the bulk of the material dating from 1700 to 1876. The collection includes more than 10,000 historical letters and manuscripts, broadsides, photographs, prints and drawings, books and pamphlets, maps, and printed ephemera from the colonial era through the 1876 centennial of the United States. It is believed to be the most extensive existing private collection of early Americana. The collection includes such important and diverse historical treasures as unpublished papers of Revolutionary War figures and the Continental Congress; letters of several American presidents, including Thomas Jefferson; a manuscript account of the departure of the first Pony Express rider from St. Joseph, Mo.; and what may be the earliest photograph of a human face. Many of the rare books and pamphlets in the collection pertain to the early Congresses of the United States, augmenting the Library's unparalleled collection of political pamphlets and imprints. The Carson Collection adds to the Library's holdings the first presidential campaign biography, John Beckley's Address to the people of the United States with an Epitome and vindication of the Public Life and Character of Thomas Jefferson, published in Philadelphia in 1800. The book was written to counter numerous attacks against Jefferson's character, which appeared in newspapers and pamphlets during the bitter election campaign. The Rare Book and Special Collections Division shares custodial responsibility for the collection with the Library's Geography and Map Division, Music Division, Prints and Photographs Division, and the Manuscript Division.
