http://www.citydirectory.com/polk/index.htmPolk's City Directory is also know as the Criss Cross Directory or the Reverse Telephone Book.
This directory allows you to search for telephone numbers by addresses.
The Directory was designed to give a panoramic view of the entire city, street by street. All of the streets are arranged alphabetically, with each street described as to starting point, termination and relative positions to other streets and landmarks.
For each street, all house numbers are arranged in numerical progression with the intersecting streets noted at their respective crossing points. Opposite each house number is place the name of the
married man, the wife's given name is shown in parentheseses immediately after his name. In case of a place of business where the firm name is not self-explanatory, the nature if the business is indicated. Home householder (i.e. the head of the household) and, in the case of a ownership is indicated by the character "ö" Numbers and tenants in office buildings and apartment houses are sub- arranged under the street number of such buildings and apartments.
