Valdman et al.'s Louisiana Creole Dictionary, and a free spaced repetition course for learning vocabulary hosted on Memrise created by a team led by Adrien Guillory-Chatman. A first language primer was released in 2017 and revised into a full-length language guide and accompanying website in 2020. 2022 saw the publication of an anthology of contemporary poetry in Louisiana Creole, the first book written completely in the language. Geographic distribution Speakers of Louisiana Creole are mainly concentrated in south and southwest Louisiana, where the population of Creolophones is distributed across the region. St. Martin Parish forms the heart of the Creole-speaking region. Other sizeable communities exist along Bayou Têche in St. Landry, Avoyelles, Iberia, and St. Mary Parishes. There are smaller communities on False River in Pointe-Coupée Parish, in Terrebonne Parish, and along the lower Mississippi River in Ascension, St. Charles Parish, and St. James and St. John the Baptist parishes. There once were Creolophones in Natchitoches Parish on Cane River and sizable communities of Louisiana Creole-speakers in adjacent Southeast Texas (Beaumont, Houston, Port Arthur, Galveston) and the Chicago area. Louisiana Creole speakers in California reside in Los Angeles, San Diego and San Bernardino counties and in Northern California (San Francisco Bay Area, Sacramento County, Plumas County, Tehama County, Mono County, and Yuba County). Historically, there were Creole-speaking communities in Mississippi and Alabama (on Mon Louis Island); however, it is likely that no speakers remain in these areas.
