New Orleans Public Library
Alphabetical and Numerical Index of Changes in Street Names and Numbers, Old and New, 1852 to Current Date .
The original index was compiled by Gray B. Amos under the supervision of Mrs. E. D. Friedrichs, Custodian of the City Hall Archives. The project was carried out under the auspices of the Works Progress Administration (WPA) in 1938. NOPL volunteer Linda Angelocci entered data from the original typewritten index into a database from which this online version was created.
We present the online version in alphabetical order by streetname, with a separate page for each letter of the alphabet. It does not provide exact address conversions for individual buildings, but it does indicate the present "hundred block" that a given old address corresponds to. Perhaps more important, the index also identifies the cross streets between which old addresses were located. It indicates, for example, that old number 23 Felicity St. lay between Rousseau and St. Thomas Sts. and is now in the 500 block.
New Orleans street numbers were converted to the present system in the early 1890s. Prior to that time there was no standardization to the numbering process. The City Engineer prepared number conversion maps (available on microfilm in the City Archives) that show both old and new numbers for individual buildings in New Orleans. Those maps are one of several sources for information on exact address conversions. Another source, the Underwriters Inspection Bureau of New Orleans Street Rate Slips, was compiled in 1897, shortly after the new numbering system went into effect. Unfortunately, though, the Street Rate Slips do not cover the entire city. Address conversions can also be made "on the fly" by comparing the earliest Sanborn maps (or the 1883 Robinson Atlas) with Sanborns published in 1895 and later.
