James Green published this business directory shortly after the Great Fire of 1849. The fire destroyed much of St. Louis’ business district and made Green’s previous directory obsolete since many businesses and people had to relocate. The directory contains a listing of trades and professions listed alphabetically by occupation type, an alphabetical street and ward listing, as well as a listing of business advertising cards. In addition to the directory, it contains an Almanac to the city of St. Louis for the year 1850, and a detailed account of many local events of 1849, including the Great Fire and the Asiatic cholera outbreak.
