These guides are from 300 to 500 pages and more. They are divided into sections. Two or more sections give the history of the state and major cities within the state. One section is composed of driving 'tours'. Field workers traveled the area, stopping at landmarks and towns along the way, speaking with locals and making notes on their findings. This section contains descriptions and histories of many of the known plantations and plantation owners.
There is an index of famous houses, battlefields and phibodaux.lantations, as well as a bibliography (additional state resources). A historical (state) timeline is quite interesting:
 ... Alvarez de Pineda explores the Gulf Coast and reports the discovery of a great river (the Mississippi?)
 ... Jean Louis, a sailor, dies, leaving his savings for the establishment of a Charity Hospital in New Orleans.
 ... Pope Pius VI establishes the Diocese of Louisiana (second in the US)
 ... Slave insurrection in Pointe Coupee parish [The Black Rebellion]

 ... Louisiana divided into the Territory of Orleans (south of 33°) and the District of Louisiana (north of 33°).

 ... Shreveport is founded
