M'Carty & Davis were early Philadelphia booksellers and publishers. The firm, owned by William McCarty (1788?-1861) and Thomas Davis (1790?-1851), was a successor to Johnson & Warner, who were noted for publishing children's books. Jacob Johnson (1771?-1819) and Benjamin Warner (1786-1821) sold their firm in 1815 to McCarty and Davis (from the AAS M'Carty & Davis Papers finding aid).
