I have added a ton of links for Louisiana to the site. However, most of these are from Ancestry (in fact, I've added every Louisiana directory found at Ancestry to my site). There are a large number of free links from the USGenWeb project for Orleans and Jefferson Parishes; however, they were transcribed as part of a specific research project and many of the transcriptions are for selected surnames only. There are also a large number of New Orleans city directories for the years 1861 - 1923, plus 1985, listed at Footnote, which I have not yet added. As you can see, most of the links to Louisiana directories are found at subscription websites. If you know of any free directories for the state of Louisiana, please let me know!
Please note if you have African roots from Louisiana that many of these directories state if a person was "colored".
