The Emporium of Arts & Sciences (Poor, Jefferson’s Library description begins Nathaniel P. Poor, Catalogue. President Jefferson’s Library [1829] description ends , 14 [no. 920]) was published in Philadelphia from May 1812 until October 1814 and edited first by John Redman Coxe and then by Thomas Cooper. With this letter Delaplaine also enclosed a subscription list, not found, that was probably headed by Coxe’s publication prospectus for the Emporium, Philadelphia, 1 Apr. 1812. The prospectus, which also appeared in the Philadelphia Poulson’s American Daily Advertiser, 20 Apr. 1812, stated that the Emporium would print practical scientific essays from European authors and American essays “of real merit”; promised to publish on topics ranging from chemistry, mineralogy, and natural philosophy to the arts and agriculture; contended that knowledge amassed by “our transatlantic rivals” could help Americans alter their country’s destiny; and explained that the publication would contain eighty pages per issue, with the first number to appear in May 1812. TJ signed the subscription list and returned it to Delaplaine on 30 Apr., and on 15 May 1812 the publisher sent it to President James Madison, who paid for a year’s subscription but declined to add his name to the list (Madison, Papers description begins William T.
