FELCONE, JOSEPH J. New Jersey Copyright Registrations, 1791-1870. Princeton: Joseph J. Felcone Inc., 2017. 188 p. Cloth. New. Copyright registrations provide important information for local historians as well as bibliographers and book historians. Beginning about 1850 these records also offer valuable insight into regional manufacturing, popular music publishing, the production and advertising of patent medicines, and photography.

Over the next two decades, registrations of labels increased exponentially, particularly for patent medicines. By the final decade of New Jersey registrations, only one third of applications were for books and pamphlets, while a third were for labels and trademarks of New Jersey products, and the remaining third were for other forms of printed and graphic matter. The latter included sheet music; maps; charts and tables; photographs; engravings and lithographs; brochures and circulars; periodicals; and designs. The applications came from every county in the state, and from major cities as well as small towns like Smith's Landing, Atlantic County, and Pokeville, Warren County. They often record titles of books, pamphlets, and maps that either have not survived or were never published.
