City directories are a valuable tool in determining current and former occupants, owners, business names and prior use of specific addresses. Publishing of city directories for major U.S. cities began in the 1800s. Many of the earliest directories did not include street or address sections but became more robust over time. In the 1950s and 1960s, many metropolitan areas were covered in cross directories, which included a name section, street section, and a numeric telephone section.
