The first catalog was published in the 1st series of the Journal, v. 4, 1817-1824, The next was made by Isaac Hays, 1824-1834, followed by one published with the Act of Incorporation and By-Laws, 1836. Additions through 1850 are interleaved in a special library copy of the 1837 catalog. From 1850-1915, the catalogs were made by librarians J. D. Sergeant and Edw. J. Nolan. In 1915, when they were copied on the typewriter, they were then called shelf lists, duplicating the card catalog in a slightly abbreviated form. They were alphabetized by author, but no complete data or dates given. These shelf lists were used until 1943 when the Library was recataloged according to the Library of Congress system.
