The commission of the Institut de France was charged with offering a prize on linguistics, under the will of Count Volney. Formerly, this essay was thought to have been by Baron Nicolas Massias (1764-1848), who won the Volney prize in 1828. However, the note that the volume was shipped from New York precludes that.

Beginning in the 1790s, the American Philosophical Society began to accumulate vocabularies and texts written in Native American languages, guided by Thomas Jefferson's idea of using comparative linguistics to reconstruct the histories of Indian peoples and discern their origins. The American Indian Vocabularies Collection was initially assembled by the Historical and Literary Committee of the APS for publication in 1816. They include information on seventeen North American languages and one each from the Caribbean and Central America, collected between 1784 and 1828. A number of individuals were invovled in recording the vocabularies, including Benjamin Hawkins, William Thornton, David Campbell, Daniel Smith, Constantine Volney, Constantine Rafinesque, William Vans Murray, John Heckewelder, Martin Duralde, Campanius Holm, and Jefferson himself. Most followed the standardized word set established by Jefferson.

These papers include diaries (1777-1782), expense books (1794-1804), notebooks, a commonplace book, drafts of essays, excerpts from minutes of Friends' Monthly Meeting, Tortola (1741-1761), newspaper clippings, sketches, and correspondence. Also included are letters and papers of Mrs. Thornton.
